Abstract
The utility model provides a cleaning disc for a floppy drive of a computer, which comprises a cleaning disc body, wherein, the cleaning disc body comprises a write protect port and doesn't comprise an index port, or the cleaning disc body comprises an index port and doesn't comprise a write protect port; the cleaning disc body is provided with a magnetic head reading or writing window. The utility model is characterized in that the cleaning disc body is provided with the index port or the write protect port. The utility model is suitable for cleaning 5.25 inch and 3.5 inch magnetic heads of IBM personal computers and compatible computers. When matching with a corresponding cleaning program, the utility model can use the whole cleaning disc surface of the cleaning disc. Therefore, the cleaning effect can be enhanced, and the service life of the cleaning disc can be extended.
Description
The utility model relates to a kind of computer format floppy driver cleaning disc.
The cleaning disc of being sold has 5.25 inches and 3.5 inches in the market.5.25 having of inch a kind ofly promptly filled and perhaps cleaning disc carried out read/write operation for Write-protect notch is arranged, but because no index hole; computing machine can not find index hole; driver is in running order always, and magnetic head can only rest on 0 magnetic track top and clean, and finishes up to cleaning.Another kind of 5.25 inches cleaning disc has only index hole for no Write-protect notch; promptly fill perhaps cleaning disc is carried out read operation; cleaning disc inserts in the driver; owing to do not fill and permitted to write and only fill and permitted to read, must carry out manual intervention, promptly key in DIR A(or B); Format A(or B) etc. order; just can carry out the cleaning to magnetic head, finish cleaning and will carry out repeatedly operation, magnetic head also can only rest on 0 magnetic track top and clean.
The purpose of this utility model is to overcome the deficiency of active computer floppy disk cleaning disc and a kind of improved computer format floppy driver cleaning disc is provided.
The utility model provides a kind of computer format floppy driver cleaning disc; comprise that containing Write-protect notch does not contain index hole or contain the cleaning disk body that index hole does not contain Write-protect notch; clean on the disk body and all have magnetic head read/write window, it is characterized in that having index hole or Write-protect notch on the described cleaning disk body.The utility model is applicable to the cleaning of 5.25 inches and 3.5 inches magnetic heads of IBM PC and compatible, with the supporting use of corresponding cleaning program, can use whole cleaning cards of cleaning disc, strengthens cleaning performance, prolongs the serviceable life of cleaning disc.
Above-mentioned index hole is opened on the cleaning sheet that cleans disk body.
Above-mentioned Write-protect notch is opened at the seal protection that cleans disk body and is put.
When using the utility model that magnetic head is cleaned, magnetic head has the motion except common circumferencial direction at magnetic track, and radial direction also produces access, and the motion of this two directions has strengthened cleaning performance.
Above-mentioned Write-protect notch is a Contraband shape.
Above-mentioned Write-protect notch is the degree of lip-rounding.
The utility model and " Replication Tools case software " (The finot Group company distribution, copyright date 1987-89) or 3.0 above versions are supporting uses on IBM PC and compatible, if on other type computer, use the cleaning software of then need rearranging.During use, with options (Options) driving reel number, type and the capacity of floppy disk are selected earlier, and put format (Format) option and be in and do not carry out read/write school inspection state, with format diskette (a Format diskette) cleaning disc is carried out format manipulation then, at this moment, can find to format and can carry out smoothly, the circumferencial direction motion of magnetic track, radial direction also produces the access motion to magnetic head except common.Can utilize 40 magnetic tracks for 5.25 inches 360KB capacity setting, 5.25 inches 1.2MB capacity setting can be utilized 80 magnetic tracks.
Adopt cleaning disc provided by the utility model, magnetic head has the motion except common circumferencial direction at magnetic track, and radial direction also produces access, and the motion of this two directions has strengthened cleaning performance.To 5.25 inches cleaning discs, it is 80 magnetic tracks that maximum can be utilized track number, cleaning disc is fully used, also prolonged simultaneously the serviceable life of cleaning disc greatly, the actual result that uses shows: the cleaning disc life-span is original more than 10 times, the life-span of existing cleaning disc is 15 times, and the life-span of the present utility model is more than 150 times.
