ABSTRACT:
In an optical card recording/reproducing apparatus having a multi-track read type optical head in which a reproducing light beam is radiated on a plurality of tracks on an optical card having a large number of tracks parallel to each other so as to cause a plurality of reproducing light-receiving elements to simultaneously reproduce data of the plurality of tracks on which the reproducing light beam is radiated, the light beam is moved such that the maximum or minimum address of addresses of the tracks irradiated by the light beam is located at the target track. After one multi-track reproduction is performed, the light beam is moved by the distance corresponding to the number of multi-tracks.
