Abstract
The present invention relates to a unique-number recording system which allows not-overlapping unique numbers to be generated. A unique-number acquisition section 120 of a unique-number recording apparatus 100a requests unique-number information, as required, from a unique-number management server 200 through a communication section 110. The unique-number management server 200 acquires the request from the unique-number recording apparatus 100a. A unique-number generation section 220 calculates unique numbers to be assigned to optical disks 300 according to history information stored in a history-information storage section 230 to generate unique-number information, sends it to the unique-number recording apparatus 100a, and updates the history information. The unique-number acquisition section 120 of the unique-number recording apparatus 100a acquires the unique-number information, and sends it to a unique-number recording section 130. The unique-number recording section 130 records certain unique numbers in the optical disks 300 according to the unique-number information. The present invention can be applied to an apparatus for manufacturing optical disks.
