10.0 USING A CLEANING DISK10.1 One of the problems with using different kinds of floppy disksin the field is the build up of magnetic particles on the headsurfaces, which can reduce read/write capability. Two ways toeffectively eliminate this problem are direct cleaning of theheads and proper disk management. Because the structure ofthe heads makes direct cleaning difficult, we recommend using~ cleaning disk.10.2 Recommended Cleaning Disk:Maker:.Model:Nagase SangyoCFD 5W10.3 Head Cleaning Procedure10.3.1 Dirty head surfaces can cause read errors and damage .themagnetic surfece of a disk. If these problems begin to occur,use the cleaning disk to clean the heads.10.3.2 Procedure1. Power up the disk drive and insert the cleaning disk inthe same way as a normal disk.2. Load the read/write heads against the disk.3. In order to increase the effectiveness of the cleaningdisk, the heads should come in contact with as much ofthe disk as possible. Step the carriage in and out duringcleaning.4. One cleaning should take no more than 5 minutes.5. To determine if cleaning is completed, check with aregular disk (new if possible) to see if the read/writefunctions are error free and operating normally.
