JPH0434785A - Digital audio tape with head cleaning function - Google Patents

Abstract

PURPOSE:To automatically clean a head every time when playing back a tape by providing with a cleaning tape at a start or end of a magnetic tape. CONSTITUTION:In the digital audio tape equipped with a digital recording function, a tape 6 for head cleaning is provided at the start or the finish of the tape of a magnetic tape 5 so that it can be simultaneously equipped with a head cleaning mechanism and a recording function. Thus, the dust of the magnetic tape and other dust adhered to the magnetic head can be automatically eliminated by the contact of a cleaning tape 6 with the magnetic head at the time of beginning or finishing the winding of the magnetic tape.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a digital audio tape with a head cleaning function used in an audio recording device or a playback device.

[Conventional technology]

2nd El (a) and (b) show a plan view and a front view of a conventional digital audio tape (hereinafter abbreviated as DAT). 4 is a transparent leader tape at the beginning of tape winding, and 5 is a magnetic tape.

At the beginning of tape winding, the left end of the tape has a leader tape 4 in order for the DAT player to detect the position of the beginning of tape winding.
- At the same time as magnetic tape 4 is detected, the next magnetic tape 5 is detected.
The program recorded in 1 is recognized as the first song, and from then on, the program is played back in the order of the second and third songs each time the song changes.

(Problem to be solved by the invention) Since the conventional DAT is configured as described above, the DA
When a T-player is played continuously, magnetic tape particles and other dust adhere to the head of the DAT player, eventually making playback impossible. In this case, it was necessary to clean the head using a separately prepared cleaning tape. Therefore, cleaning the head requires a lot of effort.

This invention was made in order to solve the above-mentioned problems, and by providing a cleaning tape at the beginning or end of the winding of the magnetic tape, which requires a special leaning tape for cleaning the head. An object of the present invention is to obtain a digital audio tape with a head cleaning function that can perform head cleaning.

[Means to solve the problem]

A digital audio tape with a head cleaning function according to the present invention is a digital audio tape having a digital recording function, which has a head cleaning tape at the beginning or end of a magnetic tape, and has both a head cleaning function and a recording function at the same time. It is characterized by

[For production]

In this invention, by bringing the cleaning tape into contact with the magnetic head, magnetic tape powder and other dust adhering to the magnetic head can be removed by the cleaning tape.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1(a) and 1(b) show a plan view and a front view of a DAT with a head cleaning function according to an embodiment of the present invention. In the figures, 1 is a DAT case, and 2 is a pair of cases 1. The tape is wound around glue wheels 3a and 3b, 4 is a transparent leader tape at the beginning of tape winding, and 5 is a magnetic tape. A cleaning tape 6 according to the present invention is provided between the leader tape 4 and the magnetic tape 5.

Next, the operation will be explained. When the tape is running, the DAT player first detects the tape winding start position using the leader tape 4, and then when the cleaning tape 6 runs over the magnetic head (not shown), magnetic tape particles and other particles adhering to the magnetic head are removed. Dust is removed by the cleaning team 16. After the cleaning tape 6 has run, the program recorded on the magnetic tape 5 is reproduced as usual.

In addition, in the embodiment, an example was explained in which the cleaning tape 6 was provided after the leader chip 14 at the beginning of tape winding, but the cleaning tape may be provided at the end of tape winding, or between the beginning and end of tape winding. It may be provided on both sides.

〔Effect of the invention〕

As explained above, according to the present invention, a cleaning tape is provided at the beginning or end of a DAT magnetic tape, so when cleaning the magnetic head, it is no longer necessary to use another cleaning tape as in the conventional method. The head can be automatically cleaned every time a tape is played, without the need for such troublesome work. This eliminates the fear that the magnetic head will become unable to reproduce data due to dust adhesion.
