Abstract
An optical tape record/playback apparatus is provided for recording/reproducing information signals onto an optical tape. The record apparatus comprises laser sources which are modulated in accordance with the information signals. A sequence number is recorded by the laser sources to aid in the recovery of information. 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 operations. The high packing density of the information recorded in the tape may affect the proper recovery of the recorded information. During the recording operation a sequence number is recorded in a special section of the optical tape to aid in the recovery of the recorded information signals.
