RECORDING AND PLAYBACK SYSTEM Abstract Recording and playback optical scanners are relatively movable with respect to each other and with respect to a movable recording medium such as reel of tape adapted for recording variations in applied light. The playback scanner reproduces recorded information at a time delayed with respect to the time of recording, wherein the amount of delay can vary within wide limits. When the play- back scanner is moved relative to recording scanner, the playback rate will be faster or slower than the recording rate.
