PROBLEM TO BE SOLVED: To provide a user-friendly audio disk which can record mainly audio signals and can be played back for multiple purposes. SOLUTION: The audio disk is constituted of the following data arrays. A 1st audio recording zone includes a SAMG (simple audio manager), an AMG (audio manager), and an ATS (audio title set), and a 2nd audio recording zone is constituted of a CAMG (compressed audio manager) and a compressed audio file. In musical pieces of the ATS, linear PCM data or lossless compressed data are arranged, and in the compressed audio data, these same musical pieces are arranged in the state that they are transformed into data of a compressed system with loss such as an AAC system and an AC-3 system. In the CAMG, text information of the compressed audio file is arranged together with control information thereof. COPYRIGHT: (C)2006,JPO&NCIPI
