Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a computer (C)
PU) to record and play back digital information, to record and play back video information, to record and play back TV receivers, video tape recorders, and audio information for airplanes.
This is a recording / reproducing apparatus with a built-in magnetic tape which is most suitable for application to a flight recorder or the like for reproduction, and belongs to the latest technical field in which a magnetic tape is used as a fixed recording medium.

[0002]

2. Description of the Related Art Conventionally, in a recording / reproducing apparatus using a magnetic tape such as a tape streamer or a video tape recorder as a recording medium, the magnetic tape has to be accommodated in a tape cassette because compatibility of the magnetic tape is required. However, the compatibility of the magnetic tape is realized by the combined operation of the attachment / detachment of the tape cassette by the cassette loading mechanism and the loading and unloading of the magnetic tape by the tape loading mechanism.

[0003]

However, a large space is required for attaching and detaching the tape cassette by the cassette loading mechanism and for loading and unloading the magnetic tape by the tape loading mechanism. And the recording area (recording capacity) is reduced because the length of the magnetic tape cannot be increased. Also, the cassette loading mechanism and the tape loading mechanism have many wear parts,
Lack of high durability is a factor that lowers quality and reliability. In addition, the tape is easily damaged during the operation of attaching / detaching the tape cassette and loading / unloading the magnetic tape, which is a factor of reducing the durability of the magnetic tape.

[0004] Further, since it is necessary to attach and detach the tape cassette, a sealing structure that completely seals the running path of the magnetic tape cannot be taken. Recording and reproduction errors due to pacing loss and the like, and deterioration of characteristics are likely to occur. Also,
There is a problem that the latest technology cannot be flexibly introduced due to the need for compatibility of the magnetic tape. A hard disk can be used as a fixed recording medium, but the hard disk has a clearly inferior recording area when compared to a magnetic tape having the same projected area, and the hard disk has a recording capacity that is smaller than a magnetic tape. Disadvantageous.

The present invention has been made in order to solve the above-mentioned problem, and a magnetic tape which was originally used as a removable medium can be replaced with a fixed tape without compensating for compatibility like a hard disk or the like. It is an object of the present invention to provide a new recording / reproducing apparatus with a built-in magnetic tape, which is used as a recording medium, and which can be realized with high durability with a simple structure.

[0006]

According to the present invention, there is provided a recording / reproducing apparatus with a built-in magnetic tape for achieving the above object, comprising: a magnetic tape wound around a tape reel; At least recording / reproducing means for recording and reproducing information on / from the magnetic tape, and all of the magnetic tape, traveling drive means and recording / reproducing means are housed in one case, and the air in the case is agitated. It has air stirring means.

In the recording / reproducing apparatus with a built-in magnetic tape according to the present invention, the magnetic tape, the traveling drive means and the recording / reproducing means are all housed in one case.
Since the air stirring means in the case is provided, the magnetic tape can be used as a fixed recording medium in the same manner as a hard disk or the like, and the air in the case is stirred by the air stirring means. It is possible to prevent heat from being trapped in the case as much as possible.
