An optical disc device includes a disc drive unit for driving an optical disc to rotate at a constant rotating speed, and an optical head for recording and reproducing data to and from the optical disc. A recording or a reproducing timing is determined according to the access position data for setting a recording position or a reproducing position on the optical disc. At the recording or reproducing timing as determined, data is recorded or reproduced at a constant linear density.
