直角方向に移動させる移動手段である。To achieve the above object, the present invention includes a plurality of recording heads that record signals on a tape, a playback head that reproduces signals recorded on the tape, and erases data recorded in the forward and backward directions of the tape. In a magnetic head consisting of a plurality of erasing heads, the erasing heads are located at both ends of the magnetic head, and the reproducing head is located at the center of the magnetic head.
[Embodiment of the Invention] Hereinafter, an embodiment of the present invention shown in FIGS. 1 and 2 will be described. I will explain based on this. In Figure 1, the aαh serpentine recording magnetic head is used, and this magnetic head 0■ has erase heads 0υ, (11') for erasing signals (81k) recorded on the tape (T) shown in the second diagram at both ends, respectively. and,
The 0th floor playback head is located in the center and plays back the data recorded on the tape, the erase head αυ and the playback head (
13I, and an erasing head (11') is located in the middle of the playback head (131) and sends a signal to the tape (Tl).
81 recording head 0shi and (12') 'r
In the figure, arrow CX)i or CX), which is arranged and configured, is a moving means for moving the magnetic head GO in a direction perpendicular to the running direction of the tape, as in the conventional case.

ものである。Next, the tape '1 is driven from the EOT side to the EOT side, that is, in the backward direction (YAK drive, but at this time, the erase head (11'), recording head (12'), and playback head 03) are used to perform this operation with BOTt. from time to time. Then, when the tape (TI) returns to the ROT position, that is, the original position 1, the magnetic head (It) is moved again to the tape (TI).
) in the direction perpendicular to the running direction (indicated by the arrow X dimension or Y)
All you have to do is move K and repeat the same operation 8+ times as described above. [Effects of the Invention] As explained above, according to the present invention, j-, f can be easily achieved because the structure of the magnetic head is one track. Kak2
There is no need for pitch accuracy between tracks in the magnetic head that is greater than the track. Since the folded and reproduced throats are used for advancing and retracting the tape, only one is required, and therefore, an inexpensive product can be obtained, which is an excellent effect.
