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 μm to 0.82 μm. 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.
An optical recording medium in which a track on which data is to be recorded is previously formed and said track is wobbled with a signal obtained by frequency-modulating a carrier having a predetermined frequency in correspondence with address information, wherein
An optical recording medium, comprising:
An optical recording medium in which a track on which data is recorded is previously formed and wobbled with a signal obtained by frequency-modulating a carrier having a predetermined frequency in accordance with address information, comprising a linking section formed between a data block serving as a data recording unit for the track and an adjacent data block, a data size of said linking section being the same as a minimum data unit for constituting said data block, wherein said track has a wobble amplitude of 10 nm to 15 nm and a track pitch of 0.74 μm to 0.82 μm.
A method of recording data on an optical recording medium in which a track on which data is recorded is previously formed and wobbled with a signal obtained by frequency-modulating a carrier having a predetermined frequency in response to address information, comprising the steps of:
