Description

[Detailed Description of the Invention] This invention relates to an improvement of a cleaner tape for recording and reproducing heads.

When a tape recorder or video device is used for a long period of time, magnetic substances from the tape or dust in the air can adhere to the recording and playback heads.
This may cause poor playback or noise,
Furthermore, this may cause damage to the tape.

Therefore, it is necessary to periodically clean the surface of the recording or reproducing head that comes in contact with the tape, and the applicant of the present application has previously proposed a tape for cleaning the recording or reproducing head as a cleaning means.

This tape for cleaning the recording/playback head is made of plastic film and has an adhesive layer and a net-like cloth layer on one side of the tape. Therefore, it is possible to completely remove dust by scraping off dust on the head surface with the net-like cloth layer and adhering it to the adhesive layer, and almost completely removing dust. Although it has achieved an extremely excellent cleaning effect, if the above-mentioned cleaner tape is used for a long period of time, dust will gradually accumulate on the adhesive layer, and its effectiveness in trapping dust will gradually wear off. However, there is a problem in that it is not easy to distinguish between the two.Furthermore, some types of video equipment have a light receiving device in the cassette insertion section, and the light emitted toward this device is blocked by the tape. If the cleaner tape itself is white or transparent, it will be difficult to distinguish the dust that has accumulated on the tape.
Also, in the case of video equipment that operates by blocking light,
There was a problem in that because the tape could not completely block out the light, the device would not work and cleaning could not be performed.

In view of the above, the purpose of this invention is to provide a recording/playback head cleaner tape that can be used to immediately detect the accumulation of dust and can be used satisfactorily even in devices that start operating by blocking light. An adhesive layer is provided on one side of a plastic film such as polyester, and a net-like cloth layer is further formed on the adhesive layer,
It is characterized in that the plastic film or adhesive layer is black.

This invention will be explained below using examples.

FIG. 1 is an enlarged sectional view of a main part of an embodiment of this invention.

The recording/playback head cleaner tape (hereinafter simply referred to as "cleaner tape") 1 of this invention is:
An adhesive layer 3 is provided on one side of a plastic film 2 made of polyester or the like, and a cloth layer 4 made of a net-like cloth such as a silk net is provided on the surface of this adhesive layer 3. Although coloring is omitted, the plastic film 2 described above is The film 2 or the adhesive layer 3 is colored black.

In the above embodiment, the net-like cloth layer 4 is made of fibers with few feathers, such as synthetic yarns such as polyester fibers, and the yarns have a thickness of about 50μ and are woven with a number of punched pieces of 50 to 100 per inch. The one given is used.

Also, the thickness of plastic film 2 is 1 mil.
(25μ), and the total thickness of the plastic film 2, adhesive layer 3, and net-like cloth layer 4 is preferably 100μ or less.

FIG. 2 shows one state in which this invention is used, in which the cleaner tape 1 is wound and stored in a tape cassette 5.

With this configuration, simply by setting the cassette 5 in the tape recorder or video device and turning on the switch, the cleaner tape 1 runs while contacting the recording or playback head (not shown), so that the necessary parts of the head can be removed. The net-like cloth layer 4 sweeps the area cleanly. Moreover,
At this time, since the plastic film 2 or the adhesive layer 3 of the cleaner tape 1 is colored black, it can be used even if it operates by blocking light.

In order to prevent the generation of static electricity due to friction between the cleaner tape 1 and the head, the fibers constituting the net-like cloth layer 4 may be mixed with conductive fibers such as carbon fibers, or the plastic film 2 may be used.
A material containing a conductive substance added thereto may also be used.

In this case, it is convenient if the black coloring of the cleaner tape 1 is made of carbon, since it can also impart electrical conductivity at the same time.

This idea is structured as above, so
Dust adhering to the recording/playback head is captured by the adhesive layer, allowing complete cleaning.Also, if the captured dust gradually accumulates,
Since the base color of the cleaner tape is black, the accumulated dust stands out, making it easy to determine whether it is usable or not, and it can be used even with devices that operate by blocking light, making it highly versatile. It has various practical effects such as being rich in
