PROBLEM TO BE SOLVED: To provide an audio disk whose playback is easy and whose convenience of operation is good for a user in mainly recording audio signals. SOLUTION: Each ACB (audio contents block) unit is constituted of a leading audio control pack (A-CONT pack) and a plurality of A packs and V packs succeeding to it. In the A-CONT pack, information for managing the audio signals of succeeding A packs are arranged like the TOC (table of contents) information of a CD. Audio data are arranged in the A packs and, for example, closed caption data (CC) other than audio data are arranged in the V packs in addition to video data. The ACB unit is constituted of an arbitrary number of packs equivalent to 0.5 to 1.0 sec and A-CONT packs are fundamentally arranged in 0.5 sec units. COPYRIGHT: (C)2004,JPO |
