Abstract

PURPOSE:To obtain >=2 master recording tapes at the same time by composing a magnetic tape of >=2 layers of magnetic recording tapes and a magnetic circuit constitution tape, and separating the magnetic recording tape and magnetic circuit constitution tape after magnetic recording. CONSTITUTION:Information is recorded on the magnetic tape 10 by a recording head 1 and the tape reaches a capstan 4 through a monitor head 2. Then, tape separation parts 5 and 6 separate the magnetic recording tapes 11 and 12 and magnetic circuit constitution tape 13, which are taken up around tape take up parts 21-23 respectively. The magnetic tape 10 has a magnetic circuit constitution tape 13, so the same information can be recorded on the magnetic recording tapes 11 and 12 simultaneously. Thus, the two magnetic recording tapes 11 and 12 are obtained as two master tapes at the same time. The magnetic circuit constitution tape 13 can be reutilized by being demagnetized by a demagnetizing head 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic recording device, and particularly to a magnetic recording device that can simultaneously obtain two or more master recording tapes during magnetic recording.

[Conventional technology]

With conventional magnetic recording devices, it has been impossible to obtain more than one master recording tape at a time. Therefore, when two or more master recording tapes are required, there is a drawback that duplications must be made from the first master recording tape.

[Problem that the invention seeks to solve]

The problem to be solved by the present invention, that is, the object of the present invention is to provide a magnetic recording apparatus that avoids the above-mentioned drawbacks by stacking a plurality of magnetic recording tapes and performing magnetic recording simultaneously.

Means for Solving 5 Problems] The magnetic recording device of the present invention includes a magnetic tape having a structure in which a plurality of magnetic recording tapes are stacked and a magnetic circuit configuration tape is stacked on the outside, and a recording device for recording information on the magnetic tape. a head, a monitor head for reproducing recorded information, a degaussing head for demagnetizing the magnetic circuit configuration tape, a capstan for running the magnetic tape, and a magnetic recording tape for each of the magnetic tapes on which information is recorded. It has a tape separation mechanism that separates magnetic circuit configuration tapes, and a plurality of horizontal tape winding Ifis that wind each separated tape, and is configured to simultaneously record the same information on a plurality of magnetic recording tapes. Ru.

〔Example〕

Hereinafter, the present invention will be explained with reference to the drawings.

FIG. 1 is a front view of main parts showing one embodiment of the present invention.

In the figure, the magnetic recording apparatus includes a recording head 1, a monitor head 2, a capstan 4 that feeds a magnetic tape 10, tape separation units 5 and 6 that separate the magnetic tape 10, and a system that winds each separated tape. Tape winding section 21゛, 2
2, and 23, and a demagnetizer 3. Magnetic tape 10 is magnetic recording tape 11 and 1
It has a three-layer structure consisting of a tape 2 and a magnetic circuit configuration tape 13.

Information is recorded on the magnetic tape 10 by a recording medium 1, and the tape passes through a monitor head 2 and reaches a capstan 4. Thereafter, the magnetic recording tape 11 is separated by tape separating units 5 and 6.
and 12, and a magnetic circuit +14-forming tape 13, which are wound by tape winding sections 21, 22 and 23, respectively.

FIG. 2 is a cross-sectional view showing a magnetic loop generated in the magnetic chip 110 by the magnetic recording head 1. As shown in FIG.

Since the magnetic tape 10 has the magnetic circuit configuration chip 113, the same information can be recorded on the magnetic recording tapes 11 and 12 at the same time.

As described above, the two magnetic recording tapes 11 and 12 are
can be created simultaneously as two master tapes. Note that the magnetic circuit configuration tape 13 can be reused by being demagnetized by the degaussing head 3.

Furthermore, when using this magnetic recording device in a digital data recorder, etc., the signal applied to the recording head 1 has a Δ2/

Although the above magnetic recording device has been described with reference to the case where there are two magnetic recording tapes, it is also possible to configure the magnetic recording device with three or more tapes in the same manner as described above.

Furthermore, since the present invention is not limited by differences in magnetic recording methods, it can be applied to either horizontal magnetic recording methods or perpendicular magnetic recording methods.

In addition, in magnetic recording by this apparatus, a portion of the magnetic loop is removed after magnetic recording, so that there is less deterioration of recorded information due to recording magnetism.

〔Effect of the invention〕

As explained above, the present invention consists of a magnetic tape consisting of two or more layers of magnetic recording tape and magnetic circuit forming tape, and by separating the magnetic recording tape and magnetic circuit forming tape after moxibustion. This has the effect that two or more master recording tapes can be obtained at the same time.
