Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a magnetic head cleaning disk cartridge that is attached to a magnetic recording drive device using a magnetic disk cartridge to clean a magnetic head.

[Conventional technology]

A conventional magnetic head cleaning disc cartridge consists of a cartridge case consisting of an upper case and a lower case each having a magnetic head insertion port and a drive shaft insertion port at predetermined locations, and a cleaning disc rotatably housed within the case. It mainly consists of disks.

[Problem that the invention attempts to solve]

When this magnetic head cleaning disk cartridge is used in a double-sided recording type drive device, there is no problem, but when used in a single-sided recording type drive device, the following problem occurs.

That is, a single-sided recording drive device is provided with a magnetic head on one side (for example, the lower side) and a pad on the other side (for example, the upper side) for pressing the magnetic disk toward the magnetic head.

Therefore, when the magnetic head cleaning disk cartridge described above is installed in the single-sided recording type drive device to clean the magnetic head, the pad is also inserted through the magnetic head insertion port and pressed against the cleaning disk. This cleaning disk is made of non-woven fabric and has numerous irregularities on its surface, so the high-speed rotation of the cleaning disk causes abnormal wear on the pressure contact surface of the pad, resulting in a significant decrease in elasticity and Function decreases. In addition, the cleaning disk becomes clogged with abrasion powder generated from the pad, and its liquid absorption properties are reduced, making it impossible to impregnate and retain a sufficient amount of cleaning liquid in the cleaning disk.

In order to solve this problem, the magnetic head insertion opening of either the upper case or the lower case was closed with a plastic sheet, etc., to prevent the pad from entering the case through this magnetic head insertion opening. There is a magnetic head cleaning disc cartridge.

However, in this disk cartridge,
When installed inside out and inside out, the pad is inserted through the open magnetic head insertion slot and comes into contact with the cleaning disk, while the magnetic head comes into contact with the plastic sheet attached to the case and comes into contact with the cleaning disk. do not come into contact with. If the cleaning disk is rotated in such a state, the pad will wear out abnormally, while the magnetic head will not be cleaned.

In particular, the upper and lower cases have almost the same shape, and if a transparent plastic sheet is used to close the magnetic head insertion slot, the appearance
The table is difficult to distinguish, making it easy to insert the disk cartridge incorrectly.

The purpose of the present invention is to eliminate the drawbacks of the prior art, and to prevent the magnetic head cleaning disk cartridge from being inserted upside down by mistake.
To provide a magnetic head cleaning disk cartridge in which the cleaning disk and the pad do not come into contact with each other and the pad does not suffer from abnormal wear.

[Means for solving problems]

In order to achieve the above object, the present invention provides a cartridge case consisting of an upper case and a lower case each having a magnetic head and a drive shaft insertion opening at predetermined locations, and a cartridge rotatably stored inside the cartridge case. The present invention is directed to a magnetic head cleaning disk cartridge equipped with a cleaning disk.

Then, when the magnetic head cleaning disk cartridge is installed in the drive device, a magnetic head cleaning disk is placed near the magnetic head insertion opening of at least one of the upper case and the lower case of the cartridge case, and the magnetic head supporting member is not in contact with the magnetic head cleaning disk cartridge. Although the pad support member does not come into contact with it, it is characterized in that a protrusion is provided that comes into contact with the pad support member to separate the pad surface from the cleaning disk.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.
1 to 4 are diagrams for explaining the first embodiment, in which FIG. 1 is a sectional view of a magnetic head cleaning disk cartridge, FIG. 2 is an enlarged bottom view of the main part of the disk cartridge, and FIG. 3 and 4 are enlarged sectional views of essential parts showing the disk cartridge installed in the drive device.

The magnetic head cleaning disk cartridge is mainly composed of a cartridge case 1 and a cleaning disk 2 rotatably housed within the cartridge case 1.

The cartridge case 1 consists of an upper case 1a and a lower case 1b molded from hard synthetic resin, and a magnetic head insertion port 3 and a drive shaft insertion port are provided at predetermined positions in the lower cases 1a and 1b, respectively. It is formed. The magnetic head insertion port 3 of one of the upper and lower cases 1a and 1b (the upper case 1a in this embodiment) is closed by a closing film 4 such as a polyester film attached from the inner surface of the case. has been done.

The cleaning disk 2 is made of, for example, a nonwoven fabric made of polyester long fibers self-fused by heat and pressure without using a binder,
It has excellent liquid absorption properties.

A protrusion 5 is formed near the magnetic head insertion port 3 of the lower case 1b. As shown in FIG. 2, this protrusion 5 is formed in a straight line with a length approximately equal to or slightly longer than the longitudinal length of the magnetic head insertion port 3, and as shown in FIG. When installed in the drive device, it is designed so that it does not come into contact with the magnetic head support member 7 that supports the magnetic head 6, but it does come into contact with the pad support member 9 that supports the pad 8, as shown in FIG. ing.

Therefore, when this magnetic head cleaning disk cartridge is inserted into a single-sided recording drive device in a normal state, the protrusions 5 do not come into contact with the magnetic head support member 7 on the fixed side, and the disk cartridge is removed, as shown in FIG. The cartridge is set in a predetermined position, while the pad 8 is in contact with the closure film 4 and is slightly raised. Therefore, the magnetic head 6 is cleaned by the rotation of the cleaning disk 2 impregnated with and holding the cleaning disk liquid, while the pad 8 is cut off from contact with the cleaning disk 2 by the closing film 4, thereby preventing wear. will not occur.

If the magnetic head cleaning disc cartridge is inserted into a single-sided recording drive device by mistake, the pad support member 9 will be slightly lifted by the protrusion 5, as shown in FIG. 8 surface is cleaning disk 2
Since it is separated from the cleaning disk 2, there is no possibility of wear due to sliding contact with the cleaning disk 2.

5 to 8 are diagrams for explaining the second embodiment, in which FIG. 5 is a sectional view of a magnetic head cleaning disk cartridge, FIG. 6 is an enlarged plan view of the main part of the disk cartridge, and FIG. 7 and 8 are enlarged sectional views of essential parts showing a state in which the disk cartridge is attached to a drive device.

This embodiment differs from the first embodiment as follows:
The protrusion 5 is provided on both the upper case 1a and the lower case 1b, and its planar shape is approximately U-shaped so as to surround the magnetic head insertion opening 3.
The protrusion 5 is not provided on the front side of the disk cartridge so that there is no problem in inserting the disk cartridge into the drive device.

FIG. 7 shows the state in which it is installed in a double-sided recording drive, and since neither the upper nor lower protrusions 5 come into contact with the magnetic head support member 7, both the upper and lower magnetic heads 6 slide against the cleaning disk 2. Cleaning can be carried out without any problem.

FIG. 8 shows a state in which the pad support member 9 is lifted by one of the protrusions 5, so that the pad 8 is separated from the cleaning disk 2. FIG. Unlike the state shown in FIG. 4 described above, since the closing sheet 4 is not attached, the magnetic head 6 comes into sliding contact with the cleaning disk 2 to perform cleaning.

In the above embodiment, a continuous protrusion was provided near the magnetic head insertion port, but it is not necessary to provide a continuous protrusion, and the same effect can be obtained even if a plurality of discontinuous protrusions are provided. be.

[Effect of idea]

The present invention has the above-mentioned configuration, so that there is no wear on the pads even if the disc is mistakenly inserted into a single-sided recording drive device and installed upside down, and the reduction in cleaning effectiveness of the cleaning disc due to adhesion of abrasion powder is eliminated. be done.
