Title of Invention

AN OPTICAL RECORDING MEDIUM AND A METHOD FOR READING INFORMATION

Abstract An optical recording medium has prepits or pregrooves on tracks in a BCA region (101) where BCA marks (104) or other barcode-shaped marks are recorded, and the track pitch of these tracks is greater than the track pitch of a track in a read-only area (102) or read/write area used to record the actual user data or disc information. Tracking in BCA is enabled by forming prepits or pregrooves in the BCA. By making the track pitch in the BCA sufficiently wider than the track pitch in the read-only area (102) and other areas in an optical disc it is difficult to uniformly modify all of the barcode-shaped BCA marks (104) in the BCA (101). A method of reading information from the medium is also disclosed.
