Identification-information recording system, management unit, recording unit and recording control circuit

摘要

A management server has: an identification-information reproducing unit which reproduces identification information from an optical disk; an invalid-unit intrinsic-information registration section which registers the reproduced identification information; and a restriction-lifting decision section which decides, on the basis of the registered identification information and unit intrinsic information given intrinsically to every recording unit, whether the identification information can be recorded on a master optical disk. A recording unit has: a communication section which notifies the management server of the unit intrinsic information on this recording unit; an identification-information generation section which generates the identification information recorded on the master optical disk; an identification-information recording section which records the identification information on the master optical disk; and a restriction lifting section which controls the operation of the identification-information generation section and the identification-information recording section on the basis of the decision result of the restriction-lifting decision section.
