記録媒体。 It has wobble pits on both sides of the recording track,
In a sample servo type optical information recording medium in which track errors are detected using the wobble pits during information recording and reproduction, the format of the servo bite section in which servo information is preformatted is such that the track position information at the time of access can be known. an access mark, the access mark consisting of at least two pits;
Of the at least two pits, one pit is shifted toward the outer circumference with respect to the center of the track, and the other pit is shifted toward the inner circumference with respect to the center of the track, thereby forming the wobble pits on both sides of the track. An optical information recording medium characterized in that the optical information recording medium is configured such that a track signal can also be generated from at least two pits of the access mark.
