ABSTRACT:
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 lazering in case the bit value is 0 and a second area where each bit in the unique ID is recorded by the lazering 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.
