Abstract: An optical disk and a method for identifying the optical disk making 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, such as, for example, a BD-R. Specifically, a polarity upon reproducing wobble information is made to be the same in both an optical disk of groove-recording system and the optical disk of a 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: Drive information is updated to always include the recording/playback conditions determined from the most recent learning process on a data recording medium. The data recording medium has a data recording area for recording data, and a drive information area for recording drive information. The drive information includes a plurality of drive-specific information records. Each of the plural drive-specific information records defines the operating conditions of the data recording and playback apparatus when a data recording and playback apparatus that can load and access the data recording medium reads or writes data. The plural drive-specific information records are arranged chronologically according to when the information was recorded to the data recording medium.
