本発明は例えば、ビデオテープレコーダ（以下
VTRという）の回転ヘツドのクリーニングを行
なうためのヘツドクリーニングテープに関する。[Detailed Description of the Invention] [Technical Field of the Invention] The present invention is applicable to, for example, a video tape recorder (hereinafter referred to as
This invention relates to a head cleaning tape for cleaning the rotating head of a VTR (VTR).

Conventionally, when the magnetic head surface was contaminated by debris from the tape and the signal could not be extracted correctly, the head surface was wrapped for a few seconds with a wrapping tape mainly composed of abrasive material, and then recorded on a regular magnetic tape. Performing playback and checking the playback status.
Alternatively, a solvent may be applied to the head surface and wiped off with a soft cloth.

When cleaning the head using the above-mentioned wrapping tape, depending on the degree of contamination, it is necessary to repeat the wrapping and checking of the regenerated state several times. If you wrap for a long time at a time to avoid this frequency,
In some cases, the head surface was worn out more than necessary. Furthermore, when a solvent is used, the solvent damages the organic materials that assemble the head, deteriorating the performance of the head. Particularly in cases where the mechanical strength is weak, such as a video head, the head may be damaged by the force of sampling the solvent.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a head cleaning tape that does not cause excessive wear on the magnetic head and allows easy head cleaning.

The present invention achieves the above object by providing a cleaning tape in which a signal that can be reproduced by the head to be cleaned is recorded on a base surface on which a binder containing abrasive material and magnetic powder is applied and dried. It is.

る必要がある。 In the figure, 1 is a base film made of polyester material, and a binder (adhesive) 2 mixed with an abrasive and magnetic powder is applied to one surface of the base film and dried. In this case, since the purpose is to clean the head, unlike normal tape, the amount of abrasive, the material and particle size of the magnetic powder, and the roughness of the applied surface (tape surface) are adjusted so that the amount of wear on the magnetic head is large. , the tape stiffness needs to be adjusted.

A signal is recorded on the tape, which is used as the tape in this embodiment. When this tape is run on a VTR, the rotating magnetic head is polished. In this case, by setting the playback mode and stopping the tape running when the playback signal output level reaches a specified value, excessive scraping of the magnetic head can be prevented. Note that the signal output level can be determined visually from the screen, such as synchronization and color, by recording the video signal without using a measuring device.
以上述べたように本発明によれば、ヘツドクリ

As described above, the present invention is useful because it prevents the magnetic head from being excessively polished during head cleaning.
