Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a flexible disk for head cleaning for cleaning the head surface for recording/reproducing information in a flexible disk device using a flexible disk as a recording medium. be.

A flexible disk device is used as an external storage device for a personal computer or the like, and records and reproduces information on a recording medium in which a disc-shaped flexible record is housed in a jacket.

In such flexible disk devices, since the recording medium is inserted into and removed from the device, there is a relatively large amount of dirt adhering to the recording medium, and it is particularly difficult to efficiently remove dust adhering to the recording/playback head. It is requested.

[Problems that conventional technology and ideas try to solve]

As mentioned earlier, in flexible disk devices, the recording medium is a replaceable medium, so
If the recording medium is inserted into the apparatus with dust attached to it, the dust will be transferred to the head, causing a significant deterioration in the recording/reproducing performance of the head.

For this reason, it is necessary to clean the recording/playback head periodically or when a failure occurs. Conventionally, the main unit is disassembled, the head is exposed or removed, and the head is cleaned using a cotton swab soaked in alcohol. Cleaning was done by wiping the surface, but this method required disassembling the device each time, making cleaning cumbersome.

As a method to solve this problem, the following method has conventionally been used to clean the head.

That is, a flexible cleaning disk made of felt or the like having the same shape as the recording medium is made, and this disk is inserted into the device and set.
By bringing the head into contact with this felt disk, the head surface is cleaned.

However, it is not possible to clean the head simply by setting a cleaning floppy disk in the device, so in order to control the device (head movement control), a cleaning program must be loaded in advance into the central processing unit. The need arose.

That is, before setting the cleaning floppy disk, insert a normal medium containing a cleaning program into the device, and once the cleaning program has been loaded, set the cleaning floppy disk in the device, and then Only by executing cleaning can the head be cleaned.

It is true that this method improves the head cleaning work compared to the above-described method of disassembling the disk device and cleaning the head. This method also has the disadvantage that it is necessary to prepare two types of disks for reading the program for head cleaning and for the actual cleaning operation, and to set each disk in the apparatus, making the cleaning operation cumbersome.

[Means for solving problems]

The object of the present invention is to solve the above-mentioned drawbacks and provide a cleaning flexible disk that can simplify head cleaning work. for the cleaning of
A head cleaning device used in a floppy disk device in which a cleaning program is loaded into the central processing unit, a flexible disk for head cleaning is set in the floppy disk device, and the head is cleaned under the control of the cleaning program. The flexible disk for head cleaning has a cleaning area where the head comes into contact to clean the head surface, and an area where a cleaning program for controlling movement of the head in the cleaning area is recorded. This can be achieved by a flexible disk for head cleaning characterized by having the following.

[Effect]

In other words, with the flexible disk for cleaning of the present invention, simply by setting this disk in the device, it is possible to load the cleaning program to the central processing unit and clean the head, which greatly reduces the work of cleaning the head. It becomes possible to improve.

〔Example〕

The figure shows a flexible disk for head cleaning according to the present invention, and the disk 1 is housed in a jet set 2 indicated by a dotted line.

The gear set 2 is provided with an elongated hole for contacting the head 3 and a round hole for rotating the disk 1.

The outer periphery of the disk 1 is a storage area 1a, and the inner periphery is a clean area 1b.

The storage area 1a is a magnetic surface like a normal disk, and the clean area 1b is covered with felt material, for example.

A head cleaning program is stored in the storage area 1a.

This information is a program for controlling the movement of the head 3 in the clean area 1b.

Now, when such a flexible disk 1 is set in the main body of the apparatus, the head 3 first reads a cleaning program from the storage area 1a, and the program is loaded into the central processing unit connected to the apparatus.

The central processing unit controls the movement of the head 3 according to this program. The command, for example, controls the head to reciprocate several times at a constant speed from the inner circumference to the outer circumference of the clean area 1b.

Note that the arrangement relationship between the clean area 1b and the storage area 1a is not limited to that shown in the figure, and the storage area 1a may be placed on the inner periphery and the clean area 1b on the outer periphery. In between,
The clean area 1b may be divided and provided on the outer periphery.

In any case, when the power of the disk device is turned on, the head 3 is often set to move to a predetermined position (home position), so the storage area 1a is located at the position corresponding to the home position. It is good to have a

[Effect of idea]

As described above, according to the present invention, there is no need to perform any special work when cleaning the head, and cleaning can be performed simply by setting the flexible cleaning disk of the present invention in the device, which greatly improves operability. improves.

Claims (1)

[Claims for Utility Model Registration] In order to clean the head of a floppy disk device connected to a central processing unit, a cleaning program is loaded into the central processing unit, and a flexible head cleaning program is loaded into the floppy disk device. A flexible disk for head cleaning is used in a floppy disk device in which a disk is set and the head is cleaned under the control of the cleaning program. 1. A flexible disk for head cleaning, comprising: a cleaning area for cleaning a surface; and an area in which a cleaning program for controlling movement of the head in the cleaning area is recorded.
