ABSTRACT:
An optical information recording/reproducing apparatus includes a first spot forming system for forming a first recording light spot and a second recording light spot for recording information on an information recording medium, a second spot forming system for forming a first reproducing light spot and a second reproducing light spot for reproducing information from the information recording medium, and a moving device for effecting a relative reciprocating motion between the first and second spot forming systems and the information recording medium. The spot forming systems form the recording light spots and the reproducing light spots in a particular arrangement.
