<p>A unique number recording system capable of producing a unique number having no like. A unique number acquiring unit (120) of a unique number recording device (100a) requests a unique number managing server (200), if necessary, for unique number information through a communication unit (110). The unique number managing server (200) receives the request from the unique number recording device (100a). On the basis of the history information stored in a history information storing unit (230), a unique number producing unit (220) calculates a unique number to be assigned to an optical disk (300), produces the unique number information, transmits the information to the unique number recording device (100a), and updates the history information. The unique number acquiring unit (120) of the unique number recording device (100a) acquires and transmits the unique number information to a unique number recording unit (130). On the basis of the unique number information, the unique number recording unit (130) records the predetermined unique number in the optical disk (300). The unique number recording system can be applied to an apparatus for manufacturing an optical disk.</p> |
