Abstract:
1. An identification-information recording system, comprising: a recording unit which records, onto a master optical disk, identification information including unit intrinsic information given intrinsically to every recording unit; and a management unit which manages the recording of the identification information onto the master optical disk, wherein: the management unit includes a reproducing section which reproduces first identification information from an optical disk manufactured using a first master optical disk, and a registration section which extracts and registers at least a part of the first identification information reproduced by the reproducing section; the recording unit includes a hold section which holds the unit intrinsic information about this recording unit, and a notification section which notifies the management unit of the unit intrinsic information held in the hold section before second identification information is recorded onto a second master optical disk; the management unit further includes a decision section which decides whether the second identification information can be recorded onto the second master optical disk in the recording unit, based on the registration information of the registration section and the unit intrinsic information on the recording unit sent from the notification section of the recording unit; and the recording unit further includes an identification-information generation section which generates the second identification information including the unit intrinsic information held in the hold section, an identification-information recording section which records the second identification information onto the second master optical disk, and a recording control section which, based on the result of a decision made by the decision section of the management unit, controls the recording of the second identification information onto the second master optical disk.
