Abstract: An optical disk and a method for identifying the optical disk are provided which make it possible to identify a recording system of the optical disk easily in a short time by a recording and reproduction apparatus when a groove-recording system and a land-recording system are both employed in one kind of optical disk, for, example, a BD-R. Specifically, the polarity upon reproducing the wobble information is made to be the same in both of the optical disk of groove-recording system and the optical disk of land-recording system. The recording system of the optical disk that shows the same wobble polarity irrespective of the recording system can be easily detected by finding a tracking polarity that can recognize the wobble information by changing the tracking polarity, whereby the start-up time of the recording and reproduction apparatus can be shortened.

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.
