ABSTRACT:
A back spacing apparatus includes a first means for providing speed information (E3, E4) corresponding to the speed of a tape, a drive source for rewinding the tape toward a supply reel (24) for back spacing, and a second means for providing an amount of electrical energy corresponding to the speed information (26) to the drive source (26) so that a length of the tape over which it is rewound toward the supply reel for back spacing is changed according to the transporting speed of the tape. The magnitude of the electrical energy is changed according to the speed information of the tape so that an amount of memory contents on that portion of a recorded tape rewound toward the supply reel for back spacing is made substantially independent of the transporting speed of the tape.
