、ＦＭ変調。Structure of a conventional example and its problems A conventional example is shown in FIG. 1 and will be described below. In the figure, 1
3 is a disk-shaped flexible magnetic recording medium (hereinafter referred to as a magnetic sheet) rotated at a slow speed by a motor 2, and 3 is a magnetic head. A video signal input through the video input terminal 4 is input to a video processor 5 and a sync separator 6, respectively. The video processor 5 performs FM modulation.
エンファシス等を行ない記録増幅器７を介して、磁気ヘ

速度制御器１３２位相制御器８に出力する。Here, the motor 2 includes an FG9 that generates a frequency that is in conflict with the rotational speed, and a PGlo that generates a pulse of 1 figure per rotation.
There are outputs to the FG sensor 11, the PG sensor 12, the speed controller 132, and the phase controller 8, respectively.

ータ２に帰還し、所望の回転数になる様に制御を行なう
。いわゆる速度制御を行なうわけである。The speed controller 13 performs f-V conversion, sample hold, etc., and feeds back to the motor 2 via the mixing amplifier 14, motor driver 16, etc., and controls the rotation speed to a desired speed. This is what is called speed control.
位相制御器８では、ＰＧセンサー１２と、同期分離器６

関係となる。いわゆる位相制御を行なうわけである。The phase controller 8 includes a PG sensor 12 and a synchronous separator 6.
The phase of each output is compared, fV conversion, sample hold, etc. are performed, and the output is output to the mixing amplifier 14. As a result, the rotational phase of the simulator 2 and the phase of the input video signal have a constant phase relationship. This is what is called phase control.

なる可能性がある。For example, if the magnetic sheet 1 recorded as described above is left in contact with the magnetic head 3 for a long time while stopped, the magnetic sheet 1 deforms and the contact state between the magnetic head 3 and the magnetic sheet 1 changes. There is a possibility that recording and playback will not be possible, unlike the initial settings.

出力が低下し、最終的に磁気シートの磁性層が取シ除か
れる（この状態を以下剥離と呼ぶ）。-Furthermore, if the same track is reproduced for a long time during reproduction, the reproduction output decreases, and the magnetic layer of the magnetic sheet is eventually removed (this state is hereinafter referred to as peeling).
この状態によシ磁気ヘッドに磁性層が付着し、別トラン
クに移動しても、記録及び再生が出来無い。In this state, the magnetic layer adheres to the magnetic head, and even if the head is moved to another trunk, recording and reproduction cannot be performed.
