LTD., a Korean Corporation of 416, Maetan-dong, Yeongtong-gu, Suwon-si, Gyeonggi-do 442-742, Republic of Korea; The following specification particularly describes the invention and ascertains the manner in which it is to be performed. WO 2005/066941 PCT/KR2004/003460 Description OPTICAL RECORDING MEDIUM, RECORDING/REPRODUCING APPARATUS AND RECORDING/REPRODUCING METHOD Technical Field [1] The present invention relates to an optical recording medium, recording/re- produang apparatus and recording/reproducing method for defect management. Background Art [2] Disc defect management is a process of compensating for data loss caused by a defect in a user data area of a disc, i.e., a defective black, by writing user data recorded in the defective block to a new portion of the user data area. Generally, disc defect management is performed using a linear replacement method or a slipping replacement method. In these methods, a defective area is replaced with a spare area having no defects. In the slipping replacement metfiod, a defective area is slipped and a next non-defective area is used. In the linear replacement method, a block of a user data area in which a defect oxurs is called a defective block. A replacement block for replacing a defective block is recorded in a spare area in a predetermined part of disc. Information on the defective block and the replacement Mock, i.e., information for searching the locations of the defective block and the replacement block, is presented in a defect list [3] Generally, when a host reads data recorded on a disc; the host determines a logical address of the data and orders a hard disc drive to read the data. Then, the hard disc drive searches for a physical address corresponding to the logical address and reads the data recorded on the disc in a location corresponding to the physical address. If a defective block oxurs in the data corresponding to the physical address, the hard disc drive has to find a replacement block that replaced the defective block. Therefore, a defect list includes defect list entries, each of the entries respectively containing information on each of the defective blocks. That is, a defect list entry is generated for each defective block, thus requiring a considerable recording space for the defect lists. Disclosure of Invention Technical Problem [41 Therefore, effective management of a space for a defect list is required. For this, effective management of information on defective blocks is required, especially for defective blocks that occurred in consecutive locations of a user data area.

Mode for Invention [35] Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are WO 2005/066941 £ PCT/KR2004/003460 described below to explain the present invention by referring to the figures. [36] FIG. 1 is a block diagram of a data receding/reproducing device according to an embodiment of the present invention. [37] Referring to FIG. 1, the data recording/reproducing device includes a writing/ reading unit 2 and a controlling unit 1. [38] The writing/reading unit 2 comprises a pickup and records/reads data on/from a disc 4 on which defects are managed according to the present invention. The controlling unit 1 performs defect management according to the present invention. In an embodiment of the present invention, the controlling unit 1 uses a verify-after-write method to find defective data by recording data by a predetermined unit and verifying the recorded data. The controlling unit 1 checks where the defective data occurs by writing and verifying user data by a recording operation unit. The controlling unit 1 generates defect information indicating where the defective data is located after checking die defective data, stores the generated information in a memory, and records die generated information on die disc as temporary defect information after collecting a predetermined amount of die generated information. [39] In an embodiment of the present invention, a recording operation, which is an operation determined by an intention of a user, or a desired recording operation, and the like, refers to an operation that includes loading die disc, recording data on the disc, and unloading die disc. During die recording operation, a verify-after-write operation is performed at least once. The temporary defect information obtained by using die verify-after-write operation is tiien temporarily stored in the memory. [40] When a user presses an eject button (not shown) in order to unload die disc, die controlling unit 1 determines that die recording operation is terminated and reads die temporary defect information stored in die memory, provides die information to me writing/reading unit 2, and causes die information to be recorded on die disc. [41] The controlling unit 1 comprises a system controller 10, a host I/F 20, a digital signal processor (DSP) 30, RFAMP 40, and a servo 50. During die recording operation, die host VF 20 receives a predetermined write command from die host 3 (in this embodiment, a computer) and transmits die write command to a system controller 10. The system controller 10 controls die DSP 30 and die servo 50 in order to perform me recording operation in die write command received from die host I/F 20. The DSP 30 adds additional data, such as a parity, to die data to be recorded which is received from me host I/F 20 in order to correct data errors, performs FCC encoding, generates an ECC block, which is an error correcting block, and modulates die ECC block in a WO 2005/066941 Xs! PCT/KR2004/003460 predetermined way. The RFAMP 40 changes data outputted from the DSP 30 into RF signals. The writing/reading unit 2 records the RF signals transmitted from the RF AMP 40 on the disc 4. The servo 50 stores recording orders inputted from the system controller 10 and servooontrols the pickup of the writing/reading unit 2. [42] The system controller 10 includes a defect management unit 11 and a memory unit 12 in order to manage defects. The defect management unit 11 reads temporary defect information stored in the memory unit 12, collects the temporary defect information, and then generates a defect list according to the present invention. That is, when the defect management unit 11 finds information on consecutive defective blocks among the read defect information, the defect management unit 11 generates a consecutive defect list entry comprised of a start entry, corresponding to information on the first defective block of the consecutive defective blocks, and an end entry, corresponding to information on the last defective block of the consecutive defective blocks. Therefore, even if, for example, eight defective blocks occur consecutively, only two entries instead of eight entries are generated, because the entries are generated not for each of the eight blocks but only for the first block and the last block of the eight consecutive defective blocks. Thus, a space required to store the entries can be reduced. The defect management unit 11 also generates a DL entry that includes consecutive defect information, showing whether a defect is a consecutive or a singular defect, and replacement state information, showing whether tiiere is a replacement block or not The defect management unit 11 generates a DL including such a DL entry. [43] To reproduce data, the host I/F 20 receives a read command from the host 3. The system controller 10 performs initialization required for reproducing. The writing/ reading unit 2 projects a laser beam onto the disc 4, and outputs an optical signal obtained by receiving a laser beam reflected from the disc 4. The RF AMP 40 changes the optical signal outputted from the writing/reading unit 2 into an RF signal, sends modulated data obtained from the RF signal to the DSP 30, and sends a servo control signal obtained from the RF signal to the servo 50. The DSP 30 demodulates the modulated data and performs ECC error correction on the demodulated data. The servo 50 servo controls the pickup after receiving both a servo signal from the RF AMP 40, and an order that is necessary to control a servo received from the system controller 10. The host I/F 20 sends data received from the DSP 30 to the host 3. For controlling the reproduction of data, the system controller 10 controls the servo 50 to read data from the location where the data is recorded. [44] A structure of an optical disc on which defects are managed according to an WO 2005/066941 ^ PCT/KR2004/003460 embodiment of the present invention is as follows. [45] Disc management information (DMI) recorded on the optical disc according an embodiment of to the present invention includes a disc definition stricture (DDS), recording management data (RMD), and a defect list (DL) A disc management area (DMA) on which DMI is recorded includes a temporary disc management area (TDMA) to record temporary DMI when the disc is recorded, and a finalized disc management area (FDMA) to record finalized DMI. [46] The TDMA to recording the temporary DMI includes a DDS/RMD area to record a DDS and RMD, and a DL area to recording a DL. [47] The DDS includes location information regarding an SA/DL area in which a re- placement block, replacing a defective block when a defect occurs in a data block recorded in a data area, and a DL is recorded, location information regarding a DDS/ RMD area, location information regarding where the DL is recorded, location information that can be used to replace data in the SA/DL area or to update the DL, a consistency flag to check whether the disc was normally ejected while being used, and write protect information to protect writing. [48] The RMD, which is information regarding managing data recorded on the disc; includes R-zone entries showing the state of each R-zone in a sequential recording mode, and a bitmap showing as a bit value whether data regarding each recording unit block of a user area is recorded or not for a random recording mode. [49] The DDS/RMD area, on which to record the DDS and the RMD, is arranged in a lead-in area or lead-out area in a single recording layer disc, while die DDS/RMD area is arranged in a lead-in area, middle area, or lead-out area in a double recording layer disc. The DDS/RMD area may be allocated in a part of a data area in order to increase the number of possible updates according to the intention of a drive producer or a user when the disc is initialized for the use of a disc. [50] When no more data can be recorded on the disc, or the user wants to maintain the current state of the disc without recording additional data and use the disc only for reproducing, the finalization of a disc is performed, and the finalized disc management information is recorded in the FDMA. [51] A PC A area is arranged for a test to detect the optimum recording power from among various recording powers according to write strategies and the variables according to the write strategies. [52] FKJ. 2 is a structural diagram of a single recording layer disc according to an embodiment of the present invention. WO 2005/066941 49 PCT/KR2004/00346© 1 [53] Referring to FIG. 2, a lead-out area is formed towards the outer circumference of the disc, a lead-in area is formed towards the center of the disc, and a data area is formed between the lead-out area and lead-in area. [54] The lead-in area includes a PCA #0, FDMA #1, FDMA #2, and DDS/RMD area #0. The data area includes a user area, SA/DL area #0, and SA/DL area #1. The lead-out area includes a PCA #1, FDMA #3, FDMA #4, and DDS/RMD area #1. [55] FIG. 3 is a structural diagram of a double recording layer disc according to an embodiment of the present invention. [56] Referring to FIG. 3, a lead-in area, data area #0, and middle area #0 are arranged in one recording layer L0, while a middle area #1, data area #1, and lead-out area are successively arranged in the other recording area LI. [57] In the layer L0, the lead-in area includes a PCA #0, FDMA #2, DDS/RMD area #0, and FDMA #1. The data area includes an SA/DL area #0 and user area #0. The middle area #0 includes an FDMA #3, DDS/RMD area #2, FDMA #4, and PCA #1. On the other hand, in the layer L1, the middle area #1 includes an FDMA #3, DDS/RMD area #3, FDMA #4, and PCA #3. The data area #1 includes an SA/DL area #1 and user area #1. The lead-out area includes a PCA #2, FDMA #2, DDS/RMD area #1, and FDMA #1. [58] As shown in FIGS. 2 and 3, when a defect occurs in the user area, a replacement block replacing a defective block is recorded in the SA/DL area along with information on the defect The information on the defect includes location information regarding the defective block, location information regarding the replacement block, and information regarding a consecutive defect. [59] FKJ. 4 is a structural diagram of data of an SA/DL area according an embodiment of to the present invention. [60] Referring to FIG. 4, the SA/DL area #i includes a DL #0, replacement block #1,... replacement block #k, DL #1, replacement block #k+l,... and DL #m. [61] The DL #0, which is a defect list including information on a defect, includes ini- tialization information. [62] Replacement blocks, from the replacement block #1 to #k replacing defective blocks from the defective block #1 to #k, are located next to the DL #0. The DL #1, which is a defect list including information regarding defective blocks from the defective block #1 to #k, and regarding replacement blocks from the replacement block #1 to #k, is recorded next to replacement block #K. Replacement blocks from the replacement block #k+l to #m, replacing defect blocks from the defect block #k+l WO 2005/066941 jftO PCT/KR2004/003460 to #m, regarding defects occurring in the user area, are located next to the DL #1. [63] In this manner, a defect list, which includes information regarding a defect according to an embodiment of die present invention, is recorded in the SA/DL area, in which a replacement block replacing a defective block is also located. That is, die defect list and the replacement block are located in one area instead of a separate area. [64] FIG. 5 is a detailed structural diagram of data of DL #i illustrated in FIG. 4. [65] Referring to FIG. 5, a DL #i 200 includes a DL identifier 210, DL update counter 220, the number of DL entries 230, DL entry #1 240, and DL entry #2 250. [66] The DL identifier 210 refers to an identifier indicating a defect list That is, an identifier indicating a defect list is needed because a defect list and a replacement block are located together in an SA/DL area according to this embodiment of the present invention. [67] The DL update counter 220 is a value showing the number of updates of a defect list. [68] The number of DL entries 230 is die total number of entries included in the defect list [69] The DL entry #1 240, or DL entry #2 250, is an entry having information on a defect Examples of contents included in these DL entries are illustrated in FIG. 6. [70] FIG. 6 is a detailed structural diagram of data of a DL entry #i illustrated in FIG. 5. [71] Referring to FIG. 6, the DL entry #i 300 includes state information 310, defective block location information 320, and replacement block location information 330. [72] The state information 310 is state information on a defect represented by a cor- responding DL entry. The defective block location information 320 represents location information regarding a defective block recorded on the user area, for example, the sector number of a defective block. The replacement block location information 330 represents location information regarding a replacement block recorded on the SA/DL area, for example, die physical sector number of a replacement block. [73] The state information 310 includes replacement state information 311, having a length of 1 bit, and consecutive defect information 312, having a length of 2 bits. [74] The replacement state information 311 represents whether a defective block, which has occurred in the user area, is replaced or not. That is, the information represents whether a defective block in the user area is replaced, and a replacement block exists in the SA/DL area, or the defective block is not replaced, and a replacement block does not exist in the SA/DL area. [75] The consecutive defect information 312 represents whether the DL entry is a WO 2005/066941 *r i| PCr/KR2004/003460 1 consecutive DL entry, which represents consecutive defective blocks, and whether the DL entry is the beginning or the end of the consecutive DL entry if die DL entry is a consecutive DL entry. [76] The consecutive defective blocks and consecutive defect list entry are described hereinafter with reference to FKS. 7 and 8. [77] Referring to FIG. 7, ® through ® refer to units in which a verify-after-write operation is performed. The recording apparatus records user data up to the section ® and then returns to the first part of the section ® in order to check whether the data is properly recorded or a defect has occurred. If a defective part is detected, the part is designated as a defective area. Thus, a defect #1, which is die defective area, is designated. The recording apparatus again records the data recorded in the defect #1 in the SA/DL area. The part in which the data recorded in die defect #1 is recorded again is called a replacement #1. Then, the recording apparatus records user data up to die section @ and then returns to die first part of die section ® in order to check whether die data is properly recorded or a defect is occurred. If a defective part is detected, die part is designated as a defect #2. In die same way, a replacement #2 corresponding to die defect #2 is generated. In die section ®, a defect #3 and a replacement #3 are generated. Since a defective part is not detected in die section ®, a defective area does not exist in this section. [78] When termination of a recording operation #0 is predicted after recording and verifying up to die section © (when a user pushes an eject button or recording of user data assigned in die recording operation is completed), die recording apparatus records a DL #1, including information regarding defects #1, #2, and #3 that occurred in die sections ® to ® , in die SA/DL area. [79] During the recording operation #1, die recording device records user data up to die section © and then returns to the first part of me section ® in order to check whether the data is properly recorded or a defect has occurred. If a defective part is detected, die part is designated as a defect area. In this way, since a defect #4 and a defect #5, which are defect areas, have consecutively occurred, consecutive blocks are designated as defective blocks. The recording device again records data recorded in die defect #4 and die defect #5 in die SA/DL area. Then, die recording apparatus records user data up to die section ©, and men returns to die first part of the section © in order to check whedier die data is properly recorded or a defect has occurred. If defect #6 and defect #7, which are defective areas, have consecutively occurred, consecutive blocks are designated as defective blocks. The recording apparatus again records data recorded in WO 2005/066941 > PCT/KR2004/003460 I the defect #6 and die defect #7 in the SA/DL area. In die section ©, no defective part is detected, so a defective area does not exist. When the termination of die recording operation #1 is predicted, the recording apparatus records a DL #2, including information regarding defects #4 through #7, in the SA/DL area. [80] Defective blocks occurring in consecutive locations of the user area, such as die defects occurring in the recording operation #1, are consecutive defective blocks. The first defective block of die consecutive defective blocks is die defect #4, and die last defective block is die defect #7. [81] Replacement blocks replacing die consecutive defective blocks that consecutively occurred in predetermined locations of die user area are recorded in consecutive locations of die SA/DL area. As shown in die SA/DL area, a replacement block #4, replacing a defect #4 block, is arranged. In the next location, a replacement #5 block, replacing a defect #5 block, is arranged. In die next location, a replacement block #6, replacing a defect #6 block, is arranged. Then, in the next location, a replacement block #7, replacing a defect #7 block, is arranged. The first replacement block among die replacement blocks replacing consecutive defective blocks is a replacement block #4, and die last replacement block replacing these consecutive defective blocks is a replacement block #7. [82] When consecutive defective blocks have occurred in consecutive locations, once the location of die first block of die consecutive defective block and die location of die last block are known, die locations of die rest of die blacks included in die consecutive defective block can also be known from die locations of die first and die last blocks, due to die characteristic the defective blacks included in a consecutive defective block are located in consecutive locations. Therefore, a space required to record information regarding defects can be reduced by including only information on die first defective block of a consecutive defective block and die last defective block in information regarding defects. The same is applied to a replacement block replacing a consecutive defective block. [83] Therefore, a consecutive defect list entry showing information regarding a consecutive defective block may include a start entry and an end entry as shown in FIG. 8. [84] Referring to FIG. 8, die consecutive defect list entry includes a start entry and an end entry. Both die start entry and die end entry have die same structure as the DL entry shown in FIG. 6. The start entry contains information regarding die first defect among consecutive defects and die end entry contains information regarding die last WO 2005/066941 & f? PCT/KR2004/003460 i defect [85] The start entry includes state information, first defective block location information representing a location of the user area where the first defective block among the consecutive defective blocks is recorded, and first replacement block location information representing a location of the S A/DL area where the first replacement block replacing the first defective block is recorded. The end entry includes state information, last defective block location information representing a location of the user area where the last defective block among the consecutive defective blocks is recorded, and last replacement block location information representing a location of the SA/DL area where the last replacement block replacing the last defective block is recorded. [86] FIG. 9 is an example of the replacement state information and consecutive defect information shown in FIG. 6. [87] Referring to FIG. 9, bits representing the replacement state information are '0' and '1.' If the replacement state information 311 is '1,' a defective block corresponding to the defective block location information 320 is not replaced, and only a defect location is shown. If the replacement state information 311 is '0,' a defective block corresponding to the defective block location information 320 is replaced by a replacement block corresponding to the replacement block location information 330. [88] Bits representing the consecutive defect information are '00,' X)l,' and' 10.' If the consecutive defect information 312 is '00,' the DL entry refers not to a consecutive defect list entry but to a single defect list entry. In this case, the DL entry may refer to a defective block with a replacement or a defective block without a replacement depending on the value set as the replacement state information. In the case of a defective block with a replacement, the DL entry has defective block location information and replacement block location information. In the case of a defective block without a replacement, the DL entry only has defective block location information. [89] If the consecutive defect information 312 is '01,' the DL entry represents a start entry of a consecutive defect list entry. Therefore, as shown in FIG. 8, the DL entry has first defective block location information regarding consecutive defective blocks, and first replacement block location information regarding consecutive replacement blocks. [90] If the consecutive defect information 312 is' 10,' the DL entry represents an end entry of a consecutive defect list entry. Therefore, as shown in FIG. 8, the DL entry has last defective block location information regarding consecutive defective blocks, WO 2005/066941 Kf Iff PC17KR2004/003460 X and last replacement block location information regarding consecutive replacement blocks. [91] Evaluation of a 3 bit combination of the state information 311, having the length of 1 bit, and the consecutive defect information 312, having the length of 2 bits, is described hereinafter. [92] If the 3 bit combination is '000,' the DL entry represents a single defect list entry about a single defective block, and the state that the single defective block has a replacement block. Therefore, the DL entry has defective black location information and replacement block location information. [93] If the 3 bit combination is '100,' the DL entry represents a single defect list entry about a single defective block, and the state that the single defective block does not have a replacement block. Therefore, the DL entry has defective block location information, but does not have replacement block location information. [94] If the 3 bit combination is "001,' the DL entry represents a start entry of a consecutive defect list entry of consecutive defective blocks, and that a defective block corresponding to the start entry, which is the first defective block among the consecutive defective blocks, has a replacement block. Therefore, the DL entry has location information regarding the first defective block among the consecutive defective blocks, and location information regarding the first replacement block among consecutive replacement blocks replacing the consecutive defective blocks. [95] If the 3 bit combination is *010,' the DL entry represents an end entry of a consecutive defect list entry about consecutive defective blocks, and that a defective block corresponding to the end entry, which is the last defective block from among the consecutive defective blocks, has a replacement block. Therefore, the DL entry has location information regarding the last defective block among the consecutive defective blocks, and location information regarding the last replacement block among consecutive replacement blacks replacing the consecutive defective blocks. [96] If the 3 bit combination is '110,' the DL entry represents an end entry of a consecutive defect list entry about consecutive defective blocks, and that a defective block corresponding to the end entry, which is the last defective block from among the consecutive defective blocks, does not have a replacement block. Therefore, the DL entry has location information regarding the last defective block from among the consecutive defective blocks, but does not have location information regarding the last replacement block from among consecutive replacement blocks replacing the consecutive defective blocks.

[112] FIG. 11B is a structural diagram of a DL #k illustrated in FK3. 10B, further including information regarding the number of consecutive defect list entries. [113] The DL #k shown in FIG. 1 IB is similar to the DL #k shown in FIG. 11 A, except that the number of consecutive defect list entries 490 is further included. Referring to FIG. 10,2' is recorded as the number of consecutive defect list entries 490 because there are two consecutive defect list entries. [114] By including a field for the number of consecutive defect list entries, it is possible WO 2005/066941 XT 11 PCT/KR2004/003460 to know the number of consecutive defect list entries and die number of single defect list entries in a defect list without searching all the DL entries. The number of single defect list entries may be calculated as shown below from the number of DL entries and the number of consecutive defect list entries. [115] The number of single defect list entries = the number of DL entries - 2 x the number of consecutive defect list entries. [116] Because the consecutive defect list entries are comprised of a pair of a start entry and an end entry, the above expression can be formed. [117] For example, in the DL #K shown in FIG. 1 IB, the number of single defect list entries can be calculated as 'the number of single defect list entries = 5-2x2=1 .* [118] FIG. 11C is a structural diagram of data of a DL #k illustrated in FIG. 11B, further including information regarding die number of consecutive defect list entries having replacement state information '0', and information regarding the number of consecutive defect list entries having replacement state information '1*. [119] The DL #k shown in FIG. 11C is similar to the DL #k shown in FIG. 1 IB, except that information regarding the number of consecutive defect list entries having replacement state information V 500, and information on the number of consecutive defect list entries having replacement state information T 510, are further included. Referring to FIG. 11 A, the consecutive defect list entry having replacement state information '0' is a consecutive defect list entry comprised of DL entry #2 450 and DL entry #3 460. Because the number of the consecutive defect list entries having replacement state information '0' is one, '1' is recorded as the number of consecutive defect list entries having replacement state information '0' 500. The consecutive defect list entry having replacement state information T is a consecutive defect list entry comprised of DL entry #4 470 and DL entry #5 480. Because the number of the consecutive defect list entries having replacement state information '1' is one, T is recorded as the number of consecutive defect list entries having replacement state information T 510. [120] FIG. 12 is a flow chart illustrating a defect management method of a disc according to and embodiment of the present invention. [121] Referring to FIG. 12, the recording apparatus records user data in a data area by a unit in which a verify-after-write operation is performed 1201. Next, data recorded in operation 1201 is verified to find a part in which a defect has occurred 1202. A controlling unit 1 designates the part in which a defect occurred as a defective area, records again the data recorded in the defective area in the SA/DL area in order to WO 2005/066941 «r W PCT/KR2004/003460 X generate a replacement area, generates information regarding the defective block and the replacement block, and records the information in a memory 1203. The operations 1201 through 1203 are repeated until the termination of the recording operation is predicted. [122] When recording user data according to a user input, or the recording operation is completed and the termination of the recording operation is predicted in operation 1204, the controlling unit 1 of the recording device reads information regarding defects stored in the memory in operation 1205. [123] If information regarding consecutive defects exists among the information on the read defects, a consecutive defect list entry comprising a start entry corresponding to information regarding the first defect of the consecutive defects, and an end entry corresponding to information regarding the last defect, is generated, and a DL is also generated by including consecutive defect information showing whether a defect is a consecutive defect or a single defect, and replacement state information showing whether a replacement block exists in each DL entry in operation 1206. [124] The generated DL is recorded in the SA/DL area in operation 1207. [125] The disc defect management method described above may also be realized as a computer readable code stored on a computer-readable recording medium. The computer readable recording medium includes all kinds of recording media on which computer readable data are stored. Examples of the computer readable recording medium include a ROM, a RAM, a CD-ROM, a stereo tape, a floppy disc, and an optical date recording device. The computer readable recording medium may also be a carrier wave (for example, transmission over the Internet) In the computer readable recording media, which are distributed to computer systems connected by network, code that a computer can read by a distribution method can be stored and executed. A function program, code, and code segments for realizing the disc defect management method can be easily inferred by programmers of the technological field to which the present invention belongs.

The DL area is not 5 %- fixed, but allocated if needed when the SA/DL area for the spare area and DL allocated in the data area for the defect management should be updated. When no more data can be recorded on the disc or the user wants to maintain the current state of the disc without recording additional data and use the disc only for 5 reproducing, the finalization of a disc is performed and the finalized disc management information is recorded in the FDMA. The each of FDMA may be allocated so that a plurality of DMI can be recorded. The FDMA is arranged in the lead-in area and the lead-out area in the single recording layer, and arranged in the lead-in area, the intermediate area, and the lead-out area in the double recording layer. 10 FIG. 3 illustrates a DL format according to the present invention. Referring to FIG. 3, the DL includes a DL identifier representing the DL, a DL update counter counting the DL update, the number of DL entries, and DL entries. FIG. 4 illustrates the DL entry according to the present invention. Referring to FIG. 4, DL entry includes location information of the defective block, 15 location information of replacement block, and state information representing the status of the DL entry. The state information includes replacing state information and consecutive defect information as shown in FIG. 4, and the replacing state information represents whether the replacing of the defective block is performed or not. The consecutive defect information represents whether the DL entry is consecutive DL entry 20 or not. In addition, if the DL entry is the consecutive DL entry, the consecutive defect information represents whether the DL entry starts or ends. For example, 1 bit is allocated for the replacing state information, and 2 bits are allocated for the consecutive defect information. If the replacing state information bit is '1', the location of the defective block is 25 displayed without replacing, and if the replacing state information bit is '0', the defective block corresponding to the defective block location information is replaced with the replacement block. If the consecutive defective information bit is '00', the DL entry is the single DL entry having the defective block location information and the replacing block location 6 * information according to the set value of the replacing state information bit. If the consecutive defect information bit is '01', the DL entry is the beginning entry of the consecutive DL entry, and at that time, the defective block location information is the starting position of the consecutive defective blocks, and the replacing block location 5 information is the starting position of the replacing blocks that replace the consecutive defective blocks. If the consecutive defect information bit is '10', the DL entry is the end of the consecutive DL entry, and at that time, the defective block location information is the end of the consecutive defective blocks, and the replacing block location information is 10 the end of the replacing blocks for the consecutive defects. 3 bit, which is the combination of the state information of 1 bit and the consecutive defect information of 2 bit, is described hereinafter. If the 3 bit combination is "000," the DL entry represents a single DL entry about a single defective block corresponding to the defective block location information and the 15 state that the single defective has a replacement block corresponding to the replacement block location information. If the 3 bit combination is "100," the DL entry represents a single defect list entry about a single defective block corresponding to the defective block location information and the state that the single defective does not have a replacement block. 20 If the 3 bit combination is "001," the DL entry represents a start entry of a consecutive defect list entry of consecutive defective blocks and that a defective block corresponding to the start entry, which is the first defective block among the consecutive defective blocks, has a replacement block corresponding to the replacing block location information. 25 If the 3 bit combination is "010," the DL entry represents an end entry of a consecutive defect list entry about consecutive defective blocks and that a defective block corresponding to the end entry, which is the last defective block from among the consecutive defective blocks, has a replacement block corresponding to the replacing block location information. 7 * If the 3 bit combination is "101," the DL entry represents a start entry of a consecutive defect list entry corresponding to the defective block location information and that the defective block corresponding to the start entry, and the state that the defective does not have a replacement block. 5 If the 3 bit combination is "110," the DL entry represents a start entry of a consecutive defect list entry corresponding to the defective block location information and that the defective block corresponding to the end entry, and the state that the defective does not have a replacement block. FIG. 5 is a reference diagram for explaining consecutive defect information 10 according to the present invention. Referring to FIG. 5, the single defective block located at location 5 is replaced by the replacement block located at the location 55, the consecutive defective blocks located at locations 9 through 12 are replaced by consecutive replacement blocks located at locations 56 through 59, and consecutive defective blocks located at 15 locations 17 through 20 are replaced by are denoted as consecutive DL without replacement located at location 60. FIG. 6 is a diagram of a DL related to the status of FIG. 5. Referring to FIG. 6, in the first DL entry, '0' is recorded as replacement state information, '00' as consecutive defect information, '5' as defective block location 20 information, and '55' as replacement block location information. In the second DL entry, '0' is recorded as replacement state information, '01' as consecutive defect information, '9' as defective block location information, and '56' as replacement block location information. In the third DL entry, '0' is recorded as replacement state information, '10' as 25 consecutive defect information, '12' as defective block location information, and '59' as replacement block location information. In the fourth DL entry, 'V is recorded as replacement state information, '01' as consecutive defect information, '17' as defective block location information, and '00' as replacement block location information. 8 * In the fifth DL entry, T is recorded as replacement state information, '10' as consecutive defect information, '20' as defective block location information, and '00' as replacement block location information. FIG. 7 is a diagram of the DL of FIG. 6 further including total number of 5 consecutive DL entry. Referring to FIG. 7, by including the total number of consecutive DL entry field in the DL, it is possible to know the number of consecutive defect list entries and the number of single defect list entries in a defect list without searching all the DL entries. The number of single defect list entries may be calculated as shown below from the 10 total number of DL entries and the total number of consecutive defect list entries. Total number of single defect list entries = total number of DL entries - 2 x the total number of consecutive defect list entries 15 For example, as shown in FIG. 7, the total number of single defect list entries can be calculated as "the number of single defect list entries = 5-2x2=1." Because the consecutive defect list entries are composed of a pair of a start entry and an end entry, the above expression can be formed. FIG. 8 is a schematic block diagram of a recording apparatus performing the 20 method of recording data onto the recording medium. Referring to FIG. 8, the recording apparatus 200 includes a control unit 210, and a writing/reading unit 220 writing the data onto a disc 230 and reading the data from the disc 230. The writing/reading unit 220 writes the data onto the disc 230 that is the 25 information storage medium 230, and reads the recorded data. The control unit 210 controls the defect information, which is the information about the defect or replacing the defect when the defects occur, including the consecutive defective entry to be recorded on the data area of the optical recording information storage medium. According to the present invention, the control unit 210 controls so that the start g r entry and the end entry are recorded in the consecutive DL entry, and so that the defective block location information representing the location of the starting defective block and the replacing block location information representing the location of the start of the replacing block among the consecutive replacement blocks replacing the 5 consecutive defective blocks are recorded in the start entry of the consecutive DL entry. In addition, the control unit 210 controls so that the defective block location information representing the location of the ending defective block and the replacing block location information representing the location of the ending of the replacing block among the consecutive replacement blocks replacing the consecutive defective blocks 10 are recorded in the end entry of the consecutive DL entry. In addition, the control unit 210 controls so that the information representing the total number of the consecutive DL entries in the defective information, or so that the total number of the DL entries and the total number of the consecutive DL entries in the defective information. In addition, the total number of the single DL entries can be 15 calculated as "total number of DL entries - 2 x the total number of consecutive defect list entries". The above present invention can be applied to any kind of optical recording information storage medium, and particularly, can be effectively applied to the recording information storage medium for one time. 20 The above recording method may also be realized as a computer readable code stored on a computer-readable recording medium. The computer readable recording medium includes all kinds of recording media on which computer readable data are stored. Examples of the computer readable recording medium include a ROM, a RAM, a CD-ROM, a stereo tape, a floppy disc, and an optical date recording device. 25 The computer readable recording medium may also be a carrier wave (for example, transmission over the Internet). In the computer readable recording media, which are distributed to computer systems connected by network, code that a computer can read by a distribution method can be stored and executed. A function program, code, and code segments for realizing the disc defect management method can be easily inferred 10 by programmers of the technological field to which the present invention belongs.
