摘要： According to the present invention, there is provided an optical disc player adapted to record a unique ID on a read-only optical disc and positively read the unique ID from the optical disc. The optical disc (1) played with this player has a specific physical cluster in which the unique ID is to be recorded. The optical disc (1) used herein is normally molded by a molding machine using a molding die. Thereafter, a unique ID is generated for each of the optical discs (1), and high-power laser light is irradiated to a specific land in the specific physical cluster correspondingly to the bit value of the unique ID to transit the land to a pit. The physical cluster has provided therein a first area where each bit in the unique ID is recorded by the lasering in case the bit value is 0 and a second area where each bit in the unique ID is recorded by the lasering in case the bit value is 1. At the time of playback, the number of errors in the first area is compared with that in the second area to determine the value of each bit in the unique ID.

摘要： A domain wall displacement detection (DWDD) system magneto-optical recording medium forms a land 3 and a groove 4 as signal recording areas. When a domain wall displacement improvement is changed by irradiating annealing light La on a boundary wall surface 5 between the land 3 and the groove 4, the position of this annealing light is detected by an annealing light scanning position displacement detecting wobbling portion 7 formed at a portion extending along the recording track length direction of the boundary wall surface 5. The annealing light scans this wobbling portion 7, whereby a vibration amplitude of a cycle corresponding to the cycle of the wobbling portion 7 is produced to thereby detect and monitor the miniscule change of the scanning position of the annealing light with high sensitivity. Thus, in the DWDD system magneto-optical recording medium, the scanning position of the annealing light at the boundary wall surface between the land 3 and the groove 4 can be detected with high sensitivity.
