Optical recording media and recording thereon |
摘要 |
<p>An optical recording medium capable of realizing high density and reliability in a recording/reproducing operation and facilitating the process which is performed by a drive apparatus is provided. The amplitude of an amount of wobbling of a track is made to be 10 nm to 15 nm and a track pitch of the track is made to be 0.74 mu m to 0.82 mu m. These values enable large-capacity recording to be realised 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 a sector for constituting a data block. <IMAGE></p> |
