Abstract
PURPOSE:To exactly grasp life of a disk, by providing a memory area in which the number of times of use of the disk or the number of times of loading of a head is written. CONSTITUTION:A memory area in which information relating to the number of times of use of a disk is written is provided on a track of the outside circumference of a floppy disk. The information relating to the number of times of use is updated in order and is written in the memory area by a disk driving device FDD9. Subsequently, the information of the memory area is compared with a set value of a main memory 7, and when it has exceeded the set value, a CPU5 decides that the disk has attained to its life, and displays it on a CRT10. In this way, life of a disk is grasped exactly. In this regard, life of a disk is decided in the same way by using the information of the number of times of loading of a head, instead of the information of the number of times of use.
