戻す構成による。A typical rotary head type magnetic recording/reproducing device has the following configuration. That is, normal recording and/or playback is performed by winding a tape-shaped record carrier (hereinafter referred to as tape) fed from a supply reel around a rotating drum equipped with a magnetic head and winding it onto a take-up reel. be exposed. In such an apparatus, when rewinding the tape, the following means are known, for example. A first means is a configuration in which the tape is rewound while the tape is wound around the rotary drum. There is something to rotate. The second means is based on a structure in which the tape is mechanically separated from the rotating drum and then rewound.

ーターの各消費電力にまで影響を及ぼす。However, according to the conventional technology, several obstacles have arisen in reducing the size and weight of magnetic recording and reproducing devices. The first problem is that winding the tape around a rotating drum and rewinding it places a large load on the tape, which not only damages the tape, but also consumes a lot of power from the reel motor, etc. The problem arises that the size of the device increases. In particular, when reducing the diameter of the rotating drum, this problem becomes serious because the tape wrapping angle around the rotating drum increases and the tape path becomes complicated. In small-diameter rotating drums, this problem affects the power consumption of the drum motor, capstan motor, and reel motor not only during tape winding but also during recording and reproduction in order to ensure stable tape running.
第二の問題は、テープを機械的に回転ドラムから離して
から巻き戻す構成は即時巻戻し及び同時再生巻戻しが効
かない欠点がある。The second problem is that the structure in which the tape is mechanically separated from the rotating drum and then rewound has the disadvantage that immediate rewinding and simultaneous playback and rewinding are not effective.
本発明は、テープを回転ドラムに巻きつけたまま巻き戻
す構成（第二の問題を解決）としながら前記第一の問題
を解決するものである。The present invention solves the first problem while having a configuration in which the tape is rewound while being wound around a rotating drum (resolving the second problem).

本発明においては、前記テープを前記回転ドラムに巻き
つけたまま、前記回転ドラムを記録再生時とは逆の方向
に回転させることにより、前記問題を解決する。(Means for Solving the Problem) In the present invention, the above problem is solved by rotating the rotary drum in the opposite direction to that during recording and reproduction while the tape is wound around the rotary drum.
テープ進行方向と回転ドラム回転方向が同一のため、テ
ープにかかる負荷は大幅に低減され、テープ走行にとも
なうテープ傷みも軽減され、テープ走行を駆動するため
のリールモーター等の消費電力も軽減される。Since the direction in which the tape travels is the same as the rotating direction of the rotating drum, the load on the tape is significantly reduced, damage to the tape due to tape travel is also reduced, and the power consumption of the reel motor, etc. used to drive tape travel is also reduced. .

2) switches the rotating drum drive circuit (3) and rotates the drum motor (4) in reverse. The rewinding of the tape begins almost at the same time or just before the time when the drum motor (4) starts to reverse. Since the rotating drum is rotated in reverse at a speed several to 30 times faster than during recording and reproduction, the load of running the tape during rewinding is extremely light.
