Background Art [2] In general, an information storage medium is used in relation to a non-contact type optical pickup device for recording/reproducing data. A type of optical disk as an example of the information storage medium is divided into a compact disk (CD) or a digital versatile disk (DVD) based on the information recording capacity. In addition, examples of an erasable optical disk include 650 MB CD-R, CD-RW, and 4.7 GB DVD+RW. Furthermore, an HD-DVD having a recording capacity of 20 GB is being developed. [3] In order to increase the recording capacity, a shorter wavelength is used as a recording light source, and the numerical aperture of an object lens is increased. In addition, a plurality of information recording layers are used. US Patent No, 5,881,032 issued on March 9, 1999 discloses a DVD-ROM having a plurality of information recording layers. [4] A sector address structure of a disk having dual information recording layers is shown in FIG. 1 A. The disk in FIG. 1A has a first information recordicg layer L1 and a second information recording, layer L2 that have lead-in areas la and 2a and lead-out areas lb and 2b, respectively. ON the first information recording layer L1, a first sector address X is increased in a direction from an inner perimeter Rin of the disk to an outer perimeter Rout of the disk. On the second information recording layer L2, a second sector address X is increased in a direction from the outer perimeter Rout to the inner perimeter Rin of the disk. [5] On the other hand, a multi -layered optical disk having more than two information recording layers can he divided into an opposite track path (OTP) and a parallel track path (PTP) based on directions of recording/reproducing data on/from the disk- The OTP reproduces data from the fust information recording layer L1 in a direction from the inner perimeter Rin to the outer perimeter Rout and reproduces data from the second information recording layer L2 in a direction from the outer perimeter Rout to WO2005/083690 3 PCT/KR2005/000512 the inner perimeter Rin, as shown in FIG. 1B. In other words, the. track spiral directions of the OTP optical disk, are alternately formed on each of the information recording layers. In addition, FIG. 1C denotes an OTP multi-layered optical disk having first through fourth information recording layers L1, L2, L3, and L4. In the OTP multi-layered optical disk, first through fourth lead-in areas la, 2a, 3a, and 4a and first through fourth lead-out areas lb, 2b, 3b, and 4h are alternately formed at the inner perimeter regions and the outer perimeter regions of the first through fourth in- formation recording layers Ll, L2, L3, and L4 of the disk, respectively. The data is reproduced from the first information recording layer Ll in the direction from the inner perimeter Rin to the outer perimeter Rout, from the second information recording layer L2 in the direction from the outer perimeter Rout to the inner perimeter Rio, from the third information recording layer L3 in the direction from the inner perimeter Rin to the cater perimeter Rout, and from the fourtti information recording layer L4 in the direction from the outer perimeter Rout to the inner perimeter Rin [6] FIG. 2 denotes a PTP dual-layered optical disk having a first information recording layer Ll from which data is reproduced in a direction from an inoer perimeter Rin to an outer perimeter Rout and a second information recording layer L2 from which data is reproduced in a direction from the inner perimeter Rin to the outer perimeter Rout. In other words, track spiral directions of the information recording layers are the same. A first lead-in area la is formed at the inner perimeter portion of the first information recording layer L1, a first lead-out area lb is formed at the outer perimeter portion of the first information recording layer Ll, a second lead-in area 2a is formed at the inner perimeter portion of the second information recording layer L2, and a second lead-out area 2b is formed at the outer perimeter portion of the second informatioa recording layer L2. [7] In the case of a multi-layered recordable disk, the lead-in areas la, 2a, 3a, and 4a and the lead-out areas 1b, 2b, 3b, and 4b include information about the disk and various conditions about recording. Accordingly, user data can be properly recorded and reproduced when reproducing the user data from the lead-in areas 1a, 2a, 3a, and a and the lead-out areas lb. 2b, 3b, and 4b. [8] When the amount of the data to be recorded on the multi-layered information storage medium is smaller than the capacity of the information recording layers, there is an empty area on at least one information recording layer. [9] A method of processing the empty area of the information recording layer should be determined, for various information storage, media. FIG. 3 A illustrates a single- layered recordable information storage medium, and FIG. 3B illustrates a dual layered recordable information storage medium. The locations aod the capacities of lead-in areas, lead-out areas, and user data areas are fixed. WO2005/083690 4 PCT/KR2005/000512 [10] On the other hand, the data may be recorded on the entire area of the data area of the first information recording layer L1 and on a portion of the data area of the second information recording layer L2, as shown in FIG. 4. When a beam passes through the first information recording layer L1 and the second information recording layer L2, the beam may pass through a portion L1R of the first information recording layer L1 on which the data is recorded and a portion L2N of the second information recording layer L2 on which the data is not recorded, or the beam may pass through portions L1R and L2R of the first and second information recording layers L1 and L2 on which the data is recorded. Thus, when the reproducing conditions of the areas through which the beam passes are different, a reproducing characteristic may be affected. Disclosure of Invention Technical Problem [11] As described above, when determining the layout of an information storage medium, the consistency and unity with the information storage medium of a particular type should be considered and the reproducing performance of a multi-layered in- formation storage medium should be considered. In addition, it is important to improve a recording speed according to the increase of a recording capacity. [12] For example, a convenlsonal recordable DVD has a single information recording layer and a capacity of 4.7 GB. On the other hand, a conventional DVD-ROM has a capacity of 8.5 GB and dual information recording layers. However, in order to back up the data from a DVD-ROM having a capacity of 8.5 GB, a recordable DVD having the same capacity is required. In addition, a method of efficiently recording data is required to reduce a back-up time of the data.

[15] In an aspect of the present invention, the location of the lead-out area varies according to the capacity of the data area. [16] In an aspect of the present invention, the dedicated area is arranged at the outmost WO2005/083690 5 PCT/KR2005/000512 perimeter of the information storage medium. [17] In an aspect of the present invention, when an area remains between the lead-out area and the dedicated area, data is not recorded in that area. [18] In an aspect of the present invention, the dedicated area is a test area, and the location of the dedicated area is fixed. [19] According to another aspect of the present invention, there is provided a method of recording data on a recordable information storage medium having a plurality of in- formation recording layers, wherein each of the information recording layers includes a lead-in area, a user data area, a lead-out area, and a dedicated area for use with a drive, the method including performing a test on the dedicated area for the drive, dividing the amount of the uset data to be recorded into the number of the information recording layers and recording the same amount of data on each of the information recording layers, and recording. The data having a lead-out property following the dala area of each of the information recording layers. [20] According to another aspect of the present invention, there is provided a system for recording data on a recordable information storage medium having a plurality of in- formation recording layers, wherein each of the information recording layers includes a lead-in area, a user dala area, a lead-out area, and a dedicated area for a drive, including a pickup unit radiating a beam to the information storage medium, a recording/reproducing signal process unit receiving the beam reflected on the in- formation storage medium through the pickup unit and performing a signal process, and a control unit performing a test in the dedicated area for the drive and dividing the amount of user dala lo be recorded into the number of the information recording layers to record the same amounf of data on each of the information recording layers. [21] Additional aspects and/or advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

In addition, a layout for remaining areas after the recording of the data is provided to minimize a data recording Lime. Description of Drawings [23] These and/or other aspects and advantages of the invention will become apparent WO2005/083690 6 PCT/KR2005/000512 and more readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which: [24] FIG. 1A illustrates a sector address structure of a conventional DVD-ROM double- layered optical disk; [25] FIG. 1B illustrates the arrangement of lead-in areas and lead-out areas of a con- ventional DVD-ROM opposite track pack (OTP) dual-layered optical disk; [26] FIG. 1C illustrates the arrangement of lead-in areas and lead-out areas of a con- ventional OTP four-layered optical disk; [27] FIG. 2 illustrates the arrangement of lead-in areas and lead-out areas of a con- ventional DVD-ROM parallel track path (FTP) four-layered optical disk; [28] FIGS. 3A and 3B are layouts of a conventional single-layered information storage medium and a conventional dual-layered information storage medium, respectively; [29] FIG. 4 illustrates regions to which a beam is input in the case where data is recorded on portions of a conventional dual-layered information storage medium; [30] FIGS. 5A and 5B are layouts of a dual information storage medium, according to an embodiment of the present invention; [31] FIGS. 6A and 6B are layouts of a four-layered information storage medium according to another embodiment of the present invention; and [32] FIG, 7 illustrates a system of recording and/or reproducing data on/from an in- formation storage medium according to an embodiment of the present invention. Mode for Invention [33] Reference will now be made in dertail to the embodiments of the present invention, examples of which arc illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below to explain the present invention by referring to the figures. [34] An information storage medium according to an embodiment of the present invention has a plurality of information recording layers. Referring to FIG. 5A, each of the information recording layers includes a data area on which user data is recorded, and a lead-in area and a lead-out area that are arranged at an inner perimeter and an outer perimeter of the data area, respectively. [35] The information storage medium according to an embodiment of the present invention may be applied to a recordable information storage medium, and more e-f- ficiently, to a recordable information storage medium on which the amount of data, to be recorded is determined before recording data. [36] When an information storage medium includes a plurality of information recording layers, the amount of data to be recorded is divided into the number of the information recording layers in order to record the same amount of data on each of the information recording layers. In other words, the capacities and the locations of ihe data areas and WO2005/083690 7 PCT/KR2005/000512 the lead-out areas may vary according to the amount of the data to be recorded. [37] FIG. 5A illustrates an opposite track path (OTP) dual layer information storage medium, and FIG. 5B illustrates a parallel track path (FTP) dual layer information storage medium. Referring to FIG. 5 A, the dual layer information storage medium includes a first information recording layer L1 and a second information recording layer L2, and the information recording layers LI and L2 include lead-in areas 20-L1 and 20-L2, data areas 30-L1 and 30-L2, and lead-out areas 40-L1 and 40-L2, re- spectively. In addition, when the amount of data to be recorded is predetermined, the amount of data is divided into halves and each half is allotted to the data areas 30-L1 and 30-L2, respectively. The reference character C denotes the maximum of the user data to be recorded. [38] In addition, the lead-out areas 40-L1 and 40-L2 are arranged at the outer perimeters of the data areas 30-LI and 30-L2 of the information recording layers to record the data in a pattern having a lead-out property. Thus, a location of the lead-out areas 40-L1 and 40-L2 varies depending on the amount of data recorded. [39] In this case, the lead-in area and the lead-out area that are located in the middle in a data recording direction may be referred to as a middle area or a connection area. In other words, the lead-out area 40-L1 of the first information recording layer L1 and the lead-out area 40-L2 of the second information recording layer L2 in FIG. 5 A, and the lead-out area 40-Ll of the first information recording layer L1 and the lead-in area 20-L2 of the second information recording layer L2 may be referred to as the middle areas or the connection areas. [40] On the other hand, an information storage medium according to an embodiment of the present invention includes a dedicated area for use by a recording and/or re- producing apparatus (hereinafter referred to as a drive) in order for the drive to read recording inforrmation before recording user data. The dedicated area, may include., for example, a test area for performing a lest for detecting an optimum recording power of a recording medium and/or an area of recording information about recording histories of the drive. [41] However, the test in the drive is performed before recording the user data, thus it is impossible to recognize the amount of data to be recorded. Therefore, the drive cannot determine the location of performing the test. As a result, the location of a test area should be fixed. [42] Referring to FIGS. 5A and 5B, dedicated areas for use by a drive, for example, test areas 45-L1 and 45-L2 may be fixed at the outmost perimeter of the information recording layers L1 and L2. When an information storage medium is loaded in the drive, the drive performs tests using the test areas 45-L1 and 45-L2 and records data. Thereafter, the drive records the pattern having the lead-out property at the outer WO2005/083690 8 PCT/KR2005/000512 perimeter of data areas 30-L1 and 30-L2. which are set depending on the size of the data to be recorded. The lead-out property is a data pattern to prohibit a pickup from separating from an information storage medium. [43] In the case where an empty area exists in the test areas 40-L1 and 40-L2 when the recording of the pattern having the lead-out property is finished, the areas 43-Ll and 43-L2 between the lead-out areas 40-L1 and 40-L2 and the test areas 45-L1 and 45-L2. respectively, remain empty. Since the empty areas 43-Ll and 43-L2 are present, a recording time cart be reduced compared to a case where the pattern having the lead- out property is recorded at the outmost perimeter of a recording medium. In addition, in order to efficiently move a pickup between recording layers, the recording may be performed according to an OTP type. [44] FIGS. 6A and 6B illustrate an OTP multi-layered information storage medium and a PTP multi-layered information storage medium including first through fourth in- formation recording layers Ll, L2, L3, and L4, respectively. [45] The first through fourth information recording layers L1, L2, L3, and L4 include lead-in areas 20-L1, 20-L2, 20-L3. and 20-L4, data areas 30-H, 30-L2, 30-L3, and 30-L4. lead-out areas 40-L1,40-L2,40-L3, and 40-L4, and dedicated areas for a drive 45-L1,45-L2,45-L3, and 45-L4, respectively. [46] The amount of data, to be recorded is divided to be approximately equally distributed among the data areas 30-L1,30-L2, 30-L3, and 30-L4 each having the same capacity thai are formed on the first through fourth information recording layers L1, L2, L3, and L4, respectively. In addition, the lead-out areas 40-L1, 40-L2,40-L3, and 40-L4 are arranged following the data areas 30-Ll, 30-L2, 30-L3, and 30-L4 on which the user data is recorded. The reference character C designates a maximum amount of user data that may be recorded. The pattern having a lead-out property is recorded on the lead-out areas 40-L1, 40-L2, 40-L3, and 40-L4. [47] The dedicated areas 45-L1, 45-L2, 45-L3, and 45-L4 may be arranged at the outmost perimeter of the information recording layers L1, L2, L3, and L4. When areas remain between the lead-out areas 40-L1, 40-L2, 40-L3, and 40-L4 and the dedicated areas 45-L1, 45-L2, 45-L3, and 45-L4, these areas are empty 43-Ll, 43-L2, 43-L3 and 43-L4. [48] FIG. 7 illustrates a system recording/reproducing data on/from an information storage medium according to an embodiment of the present invention. [49] A system recording/reproducing data includes a pickup unit 50, a recording/re- producing signal process unit 60, and a control unit 70. More specifically, the system includes a laser diode 51 of radiating a beam, a collimating lens 52 of collimating the beam radiated from the laser diode 51, a beam splitter 54 of converting the path of the incidence beam, and an objective lens 56 of concentrating the beam from the beam WO2005/083690 9 PCT/KR2005/000512 splitter 54 on an information storage medium D. [50] The beam reflected from the information storage medium D is reflected on the beam splitter 54 and received by an optical detector, for example, a quadrant optical detector 57. The beam received by the optical detector 57 is converted into electric signals by passing through an operation circuit unit 58 and output as RF signals, In other words, channel Ch1 detects a sum of signals and differential signal channel Ch2 detects push-pull signals. [51] Referring to FIG. 5A, by way of example, the control unit 70 performs a test in test areas 45-L1 and 45-L2 of the information storage medium D before recording data on the information storage medium D. In addition, the control unit 70 records ap- proximately the same amount of user data on each of the information recording layers L1 and L2 of the informaiion storage medium D. The control unit 70 controls the pickup unit 50 to radiate a recording beam of a proper power, which is obtained by the test, to record. the user data on the information storage. medium D. When, the recording, of the user daia is finished, the pattern of a lead-out property is recorded in at least one of the lead-out areas 40-L1 or 40-L2. [52] In addition, when areas 43-L1 and 43-L2 remain between the data areas and the test areas 45-L1 and 45-L2, the control unit 70 finishes the recording without recording data on the areas 43-L1 and 43-L2 (i.e., the areas are left empty). [53] In order to reproduce the data from the information storage medium D, a beam reflected from, the information storage medium D is input to the optical detector 57 by passing through the objective lens 56 and the beam splitter 54. The signals input to the optical detector 57 are converted into electric signals by the operation circuit unit 58 and output as RF signals. [54] A method of recording data according to aspects of the present invention recognizes the amount of data to be recorded on an information storage medium when the information storage medium is loaded on a drive, and performs a test on a dedicated, area for the drive, for example, a test area of the information storage medium. Thereafter, the amount of the data is divided to allot data areas having ap- proximately the same amount on each of information recording layers. Then, the data is recorded based on the allotted amount of data, and the data having a lead-out property is recorded following the data areas on the information recording layers. [55] On the other hand, when areas remain between the lead-out areas and the dedicated areas for the drive, these areas are empty.
