ABSTRACT:
An optical card recording/regenerating apparatus performs at least either recording or regenerating while reciprocating an optical card with respect to an optical head. At this time, the apparatus drives the optical card so that the relative speed between the optical card and optical head will be constant over a data division of the optical card and part of ID divisions in the vicinities of both edges thereof. When the relative speed becomes constant, the apparatus performs at least either recording or regenerating. The apparatus offers a smaller drive length. This realizes downsizing of an optical recording/regenerating apparatus and reduction of an access time.
