Abstract
A record/playback apparatus is provided for recording/reproducing information signals in cooperation with an optical tape medium. The record apparatus comprises a laser source which is modulated in accordance with the information signals. A switching mirror, which is interposed between the laser source and the optical tape, switches the light beam emitted by the source to alternately scan helical tracks across an optical tape. In the playback mode a light detector is arranged to intercept the light reflected from the optical tape. The reflected light contains the information which was recorded on the optical tape during the recording operation.
