事にある。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The object of the present invention is to prevent wear and tear of the magnetic head during fast forwarding and rewinding in a rotating head type magnetic tape recording device.

気テープを回転磁気ヘッドから外す操作を行うので、使
用上わずられしさがあり不便であった。Conventionally, when fast forwarding or rewinding a magnetic tape, the magnetic tape was temporarily removed from the rotating magnetic head. Since it requires removal, it is cumbersome and inconvenient to use.

とにある。SUMMARY OF THE INVENTION An object of the present invention is to provide a magnetic tape recording device that reduces wear and tear on the magnetic head when fast forwarding or rewinding the magnetic tape while the magnetic tape is attached to a rotating head.
回転ヘッドに磁気テープを装着したまま早送りや巻き戻

より少なくすることで、磁気ヘッドの摩滅を少なくして
いる。When performing fast forwarding or rewinding with the magnetic tape attached to the rotating head, the number of rotations of the rotating magnetic head is lower than the normal number of rotations to reduce wear and tear on the magnetic head.

。A magnetic tape 7 is run over a rotary head by a magnetic tape feeding device comprising a capstan roller 5 and a motor 7. During normal recording or playback, the tape 7 moves at a constant speed.
In addition, two rotating heads rotate at a constant rotation speed. When fast-forwarding or rewinding, the magnetic tape 7 runs at, for example, 50 times the normal speed. At this time, since the rotary head 1 does not need to perform recording or reproduction, the rotation speed may be lowered to such an extent that the frictional resistance during running of the magnetic tape 70 does not increase.
磁気ヘッド2が磁気テープ70面を走行する量は回転ヘ
ッドの回転数に比例するので、この時の磁気ヘッド2の
摩滅を少なくする事ができる。Since the amount by which the magnetic head 2 travels on the surface of the magnetic tape 70 is proportional to the number of rotations of the rotary head, wear and tear on the magnetic head 2 at this time can be reduced.
