ABSTRACT:
In a process for manufacturing an information recording medium, a configuration is provided in which strict information management and an information recording medium manufacturing process are realized. In a configuration in which master data as original data of recording data for an information recording medium is generated and recording data for the information recording medium is generated on the basis of the master data, master data containing a dummy data area in a partial area of the master data is generated, and the dummy data area is identified and a process for setting significant information is performed on the basis of the stored information of an auxiliary file. Therefore, it is not necessary to obtain data of significant information when the master data is to be generated, and it becomes possible to generate the master data without obtaining specific information, such as an encrypted key block.
