Abstract

PURPOSE:To eliminate the interference between adjacent tracks by using recording or reproducing heads different between the positive direction and the negative direction and adjusting heights of heads in respective directions. CONSTITUTION:In a first mode, an instruction which rotates a reel motor 5 or 6 in the positive direction is sent from a CPU 23 to run a tape 1 in the position direction, and the direction is sent to a head changeover switch 22 also, and recording or reproducing heads 7 and 8 of the first mode are used to perform recording or reproducing. In a second mode, an instruction which rotates the reel motor 6 or 5 in the negative direction is sent from the CPU 23 to run the tape 1 in the negative direction, and the instruction is sent to the head changeover switch 22 also, and recording or reproducing heads 9 and 10 of the second mode are used to perform recording or reproducing. In this case, the interference between adjacent tracks is eliminated when heights of heads 7-10 are so preliminarily adjusted that they are suitable for respective directions.

うという問題があった。[Problems to be solved by the invention] In the conventional recording system as described above, even if the heights of the heads are different during unidirectional recording or playback, it is possible to achieve accurate tracking by adjusting the heights of each head. However, in the case of bidirectional recording or playback, due to variations in the thickness of the head, the height of the head in other directions cannot be adjusted, resulting in different track widths during recording, which may overlap adjacent tracks. Therefore, there was a problem in that part of the track was erased.
