ABSTRACT:
An information recording/reproducing method in which a recording area is divided into a plurality of zones in the radial direction of a disk so that the lengths of recording pits become the same in the entire recording area of the disk and the recording/reproduction of information is effected with the number of revolutions of the disk changed in each zone from the inner peripheral zone toward the outer peripheral zone. The method includes the step of effecting the recording or reproduction of the information without changing the number of revolutions if the amount of information to be recorded or reproduced is equal to or smaller than a predetermined amount when seeking is effected from a zone in which a recording/reproducing head is in a standby state to a different zone to effect the recording or reproduction.
