本発明は磁気記録再生装置に使用される磁気ヘッドを清
掃するクリーニングテープに関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cleaning tape for cleaning a magnetic head used in a magnetic recording/reproducing device.

に市場に出回るようになってきている。2. Description of the Prior Art Structure and Problems There has been a remarkable rise in the popularity of magnetic recording and reproducing devices such as video tape recorders (hereinafter abbreviated as VTR) in recent years. As the quantity of VTRs increases, cleaning tapes that remove dirt from the magnetic heads used in VTRs are also coming on the market in large quantities.

I will explain about the tape.

In the figure, 1 is a tape for cleaning the magnetic head, 2 is a tape for checking image quality, and 3 is a leader tape.

The operation will be explained below - First, the cleaning tape is set on the VTR and run. First, the magnetic head cleaning tape 1 comes into contact with the magnetic head to remove dirt attached to the magnetic head. Next, check the image quality with the image quality confirmation tape 2 to check how much dirt has been removed from the magnetic head, and determine whether further cleaning is required.If further cleaning is necessary, repeat the same operation, and if unnecessary, use the cleaning tape. stop.
ところが従来のクリーニングテープでは磁気ヘッド清掃
用テープ1の長さが同一であるため、クリーニングを適
度に実施することが困難である。However, in the conventional cleaning tape, since the length of the magnetic head cleaning tape 1 is the same, it is difficult to perform proper cleaning.
すなわち磁気ヘッド清掃用テープ1を走行させている間

ープ2により磁気ヘッドを削りすぎてしまう可能性があ
った。That is, since the image quality cannot be checked while the magnetic head cleaning tape 1 is running, there is a possibility that the magnetic head may be scraped too much by the magnetic head cleaning tape 2.
発明の目的
本発明は上記欠点に鑑み、磁気ヘッドの清掃を適度に行
いうるクリーニングテープを提供するものである。OBJECTS OF THE INVENTION In view of the above-mentioned drawbacks, the present invention provides a cleaning tape that can properly clean a magnetic head.

気ヘッドをいためることがなくなる。Structure of the Invention In order to achieve this object, the cleaning tape of the present invention is made by alternately repeating one or more sets of a tape for checking image quality and a tape for cleaning a magnetic head whose length gradually becomes shorter from the tip. This structure prevents the magnetic head from being cleaned more than necessary and prevents damage to the magnetic head.

ーニングの必要性は初期に比較して少なくなっている。First, the magnetic head is cleaned by using the magnetic head cleaning tape 1 for the first time. Next, the image quality is checked using the first image quality checking tape. If the screen returns to its original state after checking the image quality, there is no need to use the next magnetic head cleaning tape 1, so the process stops immediately. However, when cleaning has not yet been completed, the tape is further advanced and cleaning is performed, but since the first cleaning has already been completed, the need for cleaning is less compared to the initial stage.

に比べ短かいために磁気ヘッドの研摩量が少なくなる。Therefore, a second cleaning is carried out, but if the cleaning ends in the middle of the cleaning, the amount of polishing of the magnetic head will be less because the magnetic head cleaning tape 1 is shorter than the first magnetic head cleaning tape. Become.

ものがある。Effects of the Invention As described above, the present invention is capable of cleaning the magnetic head without damaging the magnetic head unnecessarily by repeating the tape for cleaning the magnetic head whose length gradually becomes shorter and the tape for checking the image quality alternately.
It can be cleaned, and its practical effects are amazing.
