Abstract
An apparatus for effecting recording and/or reproduction of information by illuminating a recording medium with a light beam. This apparatus is provided with a motor for moving the medium and the light beam, one actuator for moving the light beam in a direction transverse to information tracks, another actuator for moving an optical head in a direction transverse to the information tracks, a control circuit for moving the light beam from one track to another, and another control circuit for moving the optical head toward an area excluding the recording area of the track at a predetermined timing. A recording/reproducing method of this invention utilizes the aforesaid apparatus, after the light beam has reached the area excluding the recording area on a particular track, the light beam is moved to a different track and the optical head is then moved in the same direction as the direction of movement of the light beam at a predetermined timing. Then, the light beam scans the recording area to record or reproduce information.
