Recording apparatus and playback apparatus

Abstract

A recording apparatus, a reproducing apparatus and a multi-session disc-shaped recording medium (CD-R disc) having a first session comprised only of audio tracks, a first disc code specifying the audio session and which is recorded in the lead-in area of the first session, and a second disc code which is recorded in the remaining sessions on the CD-R disc.

Description

technical field [0001] The present invention relates to a method for recording audio data or computer data on a disc-shaped recording medium having a plurality of sectors (Session), such as a compact disc, and a recording device and a playback device using the data recording method. Background technique [0002] The first commercially available minidisc was the music CD (CD-DA: Minidisc Digital Audio), and thus the standard has recently proliferated for multimedia. Typical standards for CDs are: [0003] CD-DA (Compact Disc Digital Audio) format; [0004] CD-ROM (Compact Disk Read Only Memory) format; [0005] CD-I (Compact Disc Interactive) format; and [0006] CD-ROM / XA (CD-ROM Extended Architecture) format. [0007] The CD-DA format is the format for audio, forms the basis for other CD formats, and specifies the signal processing system and physical structure of the disc. The CD-ROM format is an extended format for comp...

Problems solved by technology

[0010] However, older generation recorders or players do not support multi-recording time discs, which, on the other hand, impose a format restriction on conventional CD-R discs, such as if a multi-sector format is used to allow multiple recording times on the same disc. - ROM devices access areas called data sectors co-existing with audio sectors, there is a danger that audio tracks cannot be played back due to the presence of codes that cannot be recognized by older generation CD players, because in this Audio data or data in the data track incorrectly replays audio data
