Method for reproducing compressed information data from a disk using a spatial frequency less than the track pitch

摘要: Method and apparatus for reproducing MPEG-compressed video data compressed audio from an optical disk having a diameter less than 140 mm and, thickness of 1.2 mm±0.1 mm, with plurality record tracks recorded thereon as embossed pits representing information exhibiting track pitch in the range between 0.646 μm 1.05 μm; being divided into lead-in area, program area lead-out area. The includes table contents (TOC) sectors at least one TOC user tracks. is comprised data, which may exhibit any difference MPEG formats, likewise format, PCM format or like. addresses start also application (ATOC) identifies various parameters accessing using information. (both user, ATOC information) encoded long distance error correction code eight parity symbols.
