摘要：
An optical disk which comprises a track groove and on which information is recorded along the track groove,
wherein the track groove (2) includes a plurality of unit sections (22,23) that are arranged along the track groove and that have side faces displaced periodically along the track groove (2), and
wherein the side faces of the unit sections (22,23) are displaced in a single fundamental period, and
wherein subdivided information allocated to each said unit section (22,23) is represented by a combination of wobble patterns selected from multiple types of wobble patterns that have been defined so as to correspond to respective signal waveforms that rise and fall mutually differently.
