Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floppy disk device head cleaning method for cleaning the magnetic head of a floppy disk device used in an information processing device.

[Conventional technology]

It has been conventional practice to clean the magnetic head of a floppy disk device using a floppy disk for head cleaning whose entire surface is coated with a special coating. By the way, when cleaning the magnetic head using a floppy disk whose entire surface is coated with a special coating, using the same track more than a certain limit may have an adverse effect on the magnetic head. The number of times the trunk was used was recorded by the user in some form, such as on a piece of paper.

[Problem to be solved by the invention]

As mentioned above, conventionally, users have to record the number of times they use a truck, which has the problem of complicating management and is prone to errors. There was also the problem that it was easy to occur.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to prevent the use of a truck more than the limited number of times reliably and without placing a burden on the user.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a floppy disk device hennode cleaning method for cleaning the magnetic head of a floppy disk device using a head cleaning floppy disk, in which the head cleaning floppy disk performs head cleaning. The floppy disk device includes a head cleaning section for cleaning the head, and a writing/reading section capable of writing and reading the number of times each area of the head cleaning section has been used, and the floppy disk device is configured to read and write the number of times each area of the head cleaning section has been used. Referring to the number of uses of each area written in the write/read section of the magnetic head, select an area whose number of uses is less than or equal to a predetermined limit, and use the selected area to write the magnetic head. cleaning is performed, and the number of uses of the area used for head cleaning is updated among the number of uses of each small page area written in the write/read section.

[For production]

The floppy disk for head cleaning includes a head cleaning section for performing head cleaning, and a write/read section in which the number of times each area of the head cleaning section has been used is written. When cleaning the magnetic head, the floppy disk device refers to the number of uses of each area written in the nodal cleaning section of the set floppy disk for head cleaning, and calculates the number of uses of the area of the head cleaning section in advance. [Example] Next, an example of the present invention will be described. This will be explained in detail with reference to the drawings.

FIG. 1 is a diagram showing an example of the configuration of a floppy disk l for head cleaning used in an embodiment of the present invention, in which a head cleaning part 11 coated with a special coating for head cleaning, a normal floppy disk and Writing/reading unit 12 that can write and continue writing in the same way
It is composed of.

FIG. 2 is a diagram showing an example of the configuration of a floppy disk device that performs head cleaning using the head cleaning floppy disk 1 shown in FIG. , a feed screw 3 that moves the magnetic field 2, a step motor 4 that rotates the feed screw 3, a drive circuit 5 for the step motor 4, a write/read circuit 6, a control circuit 7, and a keyboard 8. Contains.

FIG. 3 is a flowchart showing an example of processing of the control circuit 7 during head cleaning, and the operation of this embodiment will be described below with reference to each figure.

When performing head cleaning, the user sets the head cleaning floppy disk l and inputs a cleaning start instruction from the keyboard 8.

When a cleaning start instruction is input from the keyboard 8, the TE111 circuit 7 starts the process shown in the flowchart of FIG. 3, and first determines whether the head cleaning floppy disk 1 is a new medium (step 3).
1). Specifically, a control signal is applied to the drive circuit 5 to move the magnetic nozzle 2 onto the write/read section 12 provided on the floppy disk 1 for head cleaning, and then to move the magnetic nozzle 2 onto the read/write section 12 provided on the floppy disk 1 for head cleaning, and then to move the magnetic nozzle 2 onto the read/write section 12 provided on the floppy disk 1 for head cleaning. Based on the signal, it is determined whether a history table as shown in FIG. 4 has been created in the writing/reading section 12. Then, if a history table has been created, it is determined that the medium is not a new medium, and if a history table has not been created, it is determined that the medium is a new medium.

If it is determined that the medium is a new medium in step 1, that is, the write/read section 1 of the floppy disk 1 for head cleaning.
2, the control circuit 7 uses the write/read circuit 6 to write the initialized history table to the write/read unit 12 (step S2), and then, in step S3
Process.

As shown in FIG. 4, the history table is a table showing how many times each trunk of the head cleaning section 11 has been used for cleaning. In the example of FIG.
This indicates that the track has been used twice and has never been used since the second track. Note that the initialized history table is a history table in which the number of times each trunk has been used is all "00". If it is determined in step 31 that the medium is not a new medium, the control circuit 7 performs the process in step S3 without performing the process in step S2.

In step S3, the control circuit 7 reads the history table written in the write/read section 12 of the head cleaning floppy disk 1 using the write/read circuit 6, and uses the history table for navel cleaning according to the contents of the read history table. Performs processing to select the track to be recorded. At this time, the control circuit 7 checks the number of times each trunk has been used, and selects a predetermined number of trunks among the trucks whose number of uses has not exceeded a predetermined limit as trunks to be used for head cleaning. .

When you select the tiger or ri to be used for head cleaning,
The control circuit 7 applies a control signal to the drive circuit 5 to move the magnetic nod 2 onto the track selected in step S3, and performs head cleaning (step S4). When the head cleaning is completed, the control circuit 7 applies a control signal to the drive circuit 5 to move the magnetic head 2 onto the write/read section 12 of the floppy disk l for head cleaning.
Further, a value obtained by adding "1" to the number of times the track used for head cleaning this time is written back to the write/read section 12 using the write/read circuit 6 (step S5).
. In the above-described embodiment, the number of times each track has been used is recorded in the write/read unit 12, but when a plurality of consecutive tracks are used in one head cleaning,
Of course, the plurality of trunks may be treated as one area, and the number of uses for each area may be recorded in the write/read unit 12.

[Effects of the Invention] As explained above, the present invention includes a head cleaning section for performing head cleaning on a floppy disk for head cleaning, and a writing/reading section in which the number of times each area of the head cleaning section is used is written. When cleaning the head, the area to be used for head cleaning is selected by referring to the number of times each area has been used written in the write/read section. There is no need to manage the number of times a track is used.
The burden on the user can be reduced, and since management errors do not occur, it is possible to reliably prevent an adverse effect on the magnetic head due to the use of a track exceeding the limit number of times.
