ているので、ノイズのないｊｌＹ明な画面が得られる。Conventional configuration and its problems In a helical scan type magnetic recording/reproducing device, during normal playback, the magnetic head synchronizes with the control signal recorded on the magnetic tape. 〜Trace on a surface] Since the screen is set to 1, a clear screen without noise can be obtained.

ない、。However, during stationary, low-speed, or high-speed reproduction, the angles of the magnetic head's running trajectory and the recording track on the hoop are different, making it impossible to produce a noise-free screen.

特殊再生画像を得ている。Therefore, a magnetic head is mounted on a drive element made of two piezoelectric ceramic plates bonded together, and during static, forward and reverse low-speed or high-speed playback, a voltage is applied to the drive element to move the magnetic head across the width of the recording track on the tape. By mechanically moving in direction 1 and tracing over the recording track, a clear special reproduction image free of noise is obtained.

ステム成立が難しい。However, recently, FM recording and reproduction has been adopted for A-dio, and the number of heads has increased, making it difficult to obtain the output of the heads with conventional systems. Particularly, in a magnetic recording/reproducing apparatus using a method in which a special reproduction head is moved by a piezoelectric drive element, the number of heads increases, making it difficult to establish a system.

The object of the present invention is to provide a magnetic recording/reproducing device that can obtain information.

である。4m structure of the invention In order to achieve the above object, the magnetic 1i1 recording and reproducing device of the present invention is equipped with a plurality of fixed heads for recording and reproducing video equal numbers on a rotating cylinder, and also has static, forward and reverse low-speed heads. Or for high-speed recycling, a piezoelectric ceramic plate or a laminated i! plate made of a piezoelectric ceramic plate and a metal plate! A type 111% dynamic element equipped with two magnetic heads for special reproduction is mounted on a rotating cylinder. Furthermore, two magnetic heads for recording and reproducing audio transmission are mounted on the rotating cylinder, At the input/output No. 15 of the magnetic head, there is a pair of rotating transformers fixed to each cylinder between the rotating cylinder and the fixed cylinder, one of which is fixed to the fixed cylinder side, and the other is fixed to the fixed cylinder side.
