IDENTIFICATION-INFORMATION RECORDING SYSTEM, MANAGEMENT UNIT, RECORDING UNIT AND RECORDING CONTROL CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide an identification-information recording system capable of minimizing the diffusion of an illegal disk. SOLUTION: A management server 1 has: an identification-information reproducing unit 10 which reproduces identification information from an optical disk; an invalid-unit specific information registration unit 11 which registers the reproduced identification information; and a restriction-lifting decision unit 13 which decides, based on the registered identification information and unit intrinsic information given specifically to every recording unit, whether the identification information is recorded on a master optical disk. A recording unit 2 has: a communication section 22 which notifies the management server of the unit intrinsic information on this recording unit; an identification-information generation section 202 which generates the identification information recorded on the master optical disk; an identification-information recording section 211 which records the identification information on the master optical disk; and a restriction-lifting section 208 which controls the operations of the identification-information generation section 202 and the identification-information recording section 211 based on the decision result of the restriction-lifting decision section 13.
