Abstract

It is possible to provide an effective and strict information management in manufacturing an information recording medium and a system for realizing an information recording medium manufacturing process. Master data is generated as source data for recording data onto an information recording medium and according to the master data, recording data for the information recording medium is generated. The master data includes a dummy data area at a certain area. According to auxiliary file storage information, the dummy data area is recognized and effective information is set. Accordingly, when generating master data, there is no need of acquiring effective information data. Thus, it is possible to generate master data without acquiring particular information such as an encryption key block.

Description

technical field [0001] The present invention relates to a data processing method, an information recording medium manufacturing management system, a recording data generating device and method, and a computer program. More specifically, the present invention relates to a data processing method capable of efficiently generating recording data for an information recording medium, an information recording medium manufacturing management system for use therewith, a recording system for use therewith Data generation apparatus and method, and a computer program for use therewith. Background technique [0002] Various software data, such as audio data such as music, image data such as movies, game programs, and various application programs (hereinafter, these will be referred to as "contents"), can be stored as digital data in recording media such as , the blue laser is used on Blu-ray Disc, DVD (Digital Versatile Disc), MD (MiniDisc), and CD (Compact Disc). Specifically, a Blu-r...
