Abstract

An item text is divided into two text blocks composed of a text block 1 without copyright and a text block 2 with copyright. In the respective text blocks 1, 2, starting from the record of TXT_CAT (text category), a group composed of IDCD (identification code), TXT_SZ (text size) and TXT (actual text) is recorded. The TXT_CAT (text category) includes data concerning the presence or absence of copyright, data concerning CHRS number and a text block size.

Description

Technical field [0001] The present invention relates to a method and device for recording text data, an audio disk, a computer program, and an audio disk playback device. Background technique [0002] Currently, as recording media capable of recording and reproducing digital audio data, there are DAT (Digital Audio Tape) and MD (Mini Disc). Each of these recording media can record 74 to 120 minutes of high-quality audio data. Among them, MD has a structure that can record the audio disc name and song name in text, but cannot record other text, such as the type of music and the input source. [0003] On the other hand, next-generation disc media whose recording capacity is several to ten times that of existing media are being put into practical use. One of them is DVD-ROM (according to the DVD Specifications for Read-Only Disc), and the other is recordable and replayable optical discs, namely DVD-RW discs (according to re-recordable discs). Disc DVD standard (DVD Specifications fo...
