Title: Confidentially protection method for cd-rom sound data
Inventor: FURUYAMA HIROHISA
IPC: G11B20/12
Filed: 1990-03-02
Abstract: PURPOSE:To make the reproduction of sound impossible by a CD player by writing meaningless sound information of a Table of contents data and writing the result into a CD-ROM. CONSTITUTION:A TOC (Table of contents) part 2 is a part into which a program written in a data part 3 in a CD-ROM 1 and management information such as an address of a sound data and distinguishment of program/sound or the like are written, and the data part 3 is a part into which an actual program and sound data in the CD-ROM 1 are written. In this case, meaningless sound management information is written in a advance to the TOC data part 2 so that the sound cannot be reproduced by the CD player. Thus, the reproduction of sound by the CD player is disabled.
