Abstract

A novel recording medium capable of realizing high density, reliability in a recording/reproducing operation and facilitating the process which is performed by a drive apparatus is provided. An amplitude amount of wobbling of a track is made to be 10 nm to 15 nm and a track pitch of the track is made 0.74 .mu.m to 0.82 .mu.m. The determined values enable large-capacity recording to be realized and the recording/reproducing performance to be prevented from being deteriorated. As administration information, recommended information for a recording/reproducing operation at an inner peripheral position and an outer peripheral position is recorded. The size of data in a linking section is made to be the same as the sector for constituting a data block.
