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 DISK AND A METHOD FOR IDENTIFYING THE OPTICAL DISK ARE PROVIDED WHICH MAKE IT POSSIBLE TO IDENTITY 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 TRACKING POLARITY, WHEREBY THE START-UP TIME OF THE RECORDING AND REPRODUCTION APPARATUS CAN BE SHORTENED.
