摘要： An optical disc medium comprises a track groove, along which main information is recorded. The track groove is divided into a plurality of blocks. The plurality of blocks each include a plurality of frames. The plurality of frames each include one shape of wobbles indicating sub information, among a plurality of prescribed shapes of wobbles. The plurality of blocks each have address information. The address information is represented by a string of at least one piece of sub information represented by the shape of wobbles of at least one of the plurality of frames.

摘要： An optical disk includes a land and a groove. The optical disk has a data efficiency of 80% or more. Data is recorded on both the land and the groove. A distance between the center of the land and the center of the groove adjacent to the land is 0.28 μm or more. Thus, an optical disk having a storage capacity of 25 GB or more can be provided.

摘要： An optical disk includes a groove and a land. Data is recorded on either the land or the groove. A pitch of the groove and a pitch of the land are 0.32 μm or more. The optical disk has a data efficiency of 80% or more by adopting a format in which other types of user data are added to every plural user data sets. The data efficiency is defined by a ratio of a user data capacity that can be used by a user to a total data capacity of the optical disk.
