Abstract

PURPOSE:To prevent the failure in reading out/writing of data on a floppy disk medium by the fatigue of the medium. CONSTITUTION:The floppy disk medium device 200 has a control section 220 which integrates the number of use times and displays this number on a display mechanism 260 for the number of use times of the device 200 and executes the operation to record the number in an unused part 320 of a floppy disk medium 300 every time when the floppy disk medium 300 is used in addition to a former floppy disk device. As a result, the degree of the fatigue of the floppy disk medium is known and the failure in reading out/writing of the data on the medium by the fatigue of the floppy disk medium is prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floppy disk device which is an auxiliary storage device, and more particularly to a floppy disk device which prevents read / write failure of data on a floppy disk medium.

[0002]

2. Description of the Related Art In a conventional floppy disk device, only data sent from an information processing device such as a terminal or a word processor is recorded on a floppy disk medium, and the device itself cannot read / write due to fatigue of the medium. Does not have a built-in defense mechanism.

[0003]

The above-described conventional floppy disk device has a mechanism for recording only the data sent from the terminal device, word processor or the like to the floppy disk medium, so that the frequency of use of the floppy disk medium is high. Even if the floppy disk medium becomes unusable due to fatigue, it cannot be detected and data read / write failures frequently occur on the floppy disk medium. There are drawbacks.

An object of the present invention is to provide a floppy disk device used as an auxiliary storage device of an information processing device such as a terminal device or a word processor in which the value obtained by integrating the number of times of use of the floppy disk medium is not used. By recording this value in a portion and comparing this value with a predetermined value, the above-mentioned drawbacks are eliminated, the medium fatigue level is known, and the reading / writing of data on the medium due to the fatigue of the floppy disk medium is performed. It is an object of the present invention to provide a floppy disk device having a medium fatigue check mechanism capable of preventing the failure.

[0005]

A floppy disk device with a fatigue check mechanism for a medium according to the present invention is a floppy disk device used as an auxiliary storage device of an information processing apparatus for reading / writing data on a floppy disk medium. , Means for recording the integrated value of the number of times of reading / writing data on the floppy disk medium in an unused portion of the floppy disk medium, and for giving a warning according to the frequency of use of the floppy disk medium It has means for comparing a warning value of a predetermined value with an integrated value and displaying a warning message when the integrated value exceeds the warning value.

[0006]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a block diagram of a floppy disk device with a medium fatigue check mechanism according to an embodiment of the present invention, and FIG. 2 is a flow chart showing the operation of a control unit 220 of the present embodiment.

As shown in FIG. 1, a floppy disk device 200 of this embodiment is an I / O interface unit 210 for receiving and sending data from an information processing device 100 such as a terminal device or a word processor, and a floppy disk medium for transferring data. Data recording unit 310 in 300
Further, the date is directly read / written to the date recording unit 321 in the unused portion 320 of the floppy disk medium 300, and the usage count is directly read / written to the usage number recording unit 322 in the unused portion of the floppy disk medium 300. The drive unit 230 to perform, a clock mechanism 240 that passes the current date to the control unit 220, a date display mechanism 250 that displays the date when the floppy disk medium 300 was first used, and the number of times the floppy disk medium 300 has been used. If the date passed to the display mechanism 260 or the date display mechanism 250 has exceeded the warranty period of the floppy disk medium 300, or the number of times of use passed to the number-of-uses display mechanism 260 has exceeded the prescribed value set by the JIS standard. In the case, a warning lamp 270 for warning the operator and a control unit for managing the entire flow It consists of 20.

Next, the operation of the floppy disk device of this embodiment constructed as described above will be described.

In FIGS. 1 and 2, when the floppy disk medium 300 is set in the floppy disk device 200 (step 11), the floppy disk medium 30 is set.
The information of the date recording section 321 and the information of the number-of-uses recording section 322 written in the unused section 320 of 0 are read into the control section 220 through the drive unit 230 (No in steps 12 and 13 and No in steps 17 and 18). ,
A date display mechanism 250 and a usage count display mechanism 260, respectively
Is displayed (steps 16 and 21). At this time, if the date could not be read (step 13, Yes),
Read the date of the day from the clock mechanism 240 (step 1
4), the date is "0" as an initial value, and the date recording unit 32
1 is written (step 15). Also, the number of times of use is read from the floppy disk medium 300 (step 1
7) If the usage count cannot be read (step 1
8, Yes), "0" as an initial value (step 19)
The number of times of use is written in the daily number-of-uses recording section 322 (step 20).

Thereafter, each time an access request from the information processing apparatus 100 to the data recording section 310 of the floppy disk medium 300 through the I / O interface section 210 reaches the control section 220 (step 22), the command is executed (step 22). 23, No. 24), data read / write (R / W) is performed on the floppy disk medium 300 (step 25), the number of times of use is counted up (step 26), and the number of times of use of the floppy disk medium 300 is recorded. At the same time as it is written in the section 322 (step 27), it is displayed on the number-of-uses display mechanism 260 (step 228). This operation continues until the floppy disk medium 300 is removed from the floppy disk device 200 (step 23, Yes).

In addition, when the difference between the date displayed on the date display mechanism 250 and the current date by the clock mechanism 240 has exceeded the warranty period of the floppy disk medium 300, or the number of times of use displayed on the number-of-uses display mechanism 260. If the value exceeds the specified value defined by the JIS standard, the warning light 270 is turned on (steps 29 and 30) to notify the operator that the floppy disk medium 300 has reached the usage limit.

[0013]

As described above, the floppy disk device with a medium fatigue check mechanism of the present invention is a floppy disk device used as an auxiliary storage device of an information processing device such as a terminal device or a word processor.
By recording the value obtained by integrating the number of times the floppy disk medium has been used in the unused part of the floppy disk medium, and comparing this value with a predetermined value, the degree of media fatigue can be determined, and the fatigue of the floppy disk medium can be known. There is an effect that it is possible to prevent inability to read / write data on the medium due to.
