Abstract
Abstract AN IMPROVED APPARATUS AND METHOD FOR RECORDING AND REPRODUCING ELECTRONIC SIGNALS ON A MAGNETIC TAPE, WHEREIN ROTATABLE RECORD AND PLAYBACK HEADS ARE UTILIZED TO SCAN OBLIQUE TRACKS ON A MOVABLE MAGNETIC TAPE. THE RECORD HEAD, AFTER A RECORDING PHASE, IS MOVABLE OUT OF SCANNING RELATIONSHIP TO A NUMBER OF SIGNAL TRACKS ON A MOVABLE MAGNETIC TAPE AND THE PLAYBACK HEADS ARE MOVED INTO SUCH SCANNING RELA- TIONSHIP PRIOR TO THE PLAYBACK PHASE. THE PLAYBACK HEADS SUCCESSIVELY SCAN A SINGLE TRACK FOR EACH REVOLUTION TO PERMIT TAPE CONSERVATION. SEVERAL EMBODIMENTS OF THE APPARATUS OF THE INVENTION CAN BE USED TO CHANGE FROM THE RECORDING PHASE TO THE PLAYBACK PHASE.
