でありた。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a management method for a magnetic storage device in a small information processing device using a microprocessor [Prior Art] Due to its structure, a magnetic storage device is Maintenance must be performed every time it is used. However, in the past, magnetic storage devices have not been managed in small information processing devices using microprocessors. For this reason, it has been impossible to maintain the magnetic storage device in accordance with the usage conditions.

３を初期化する。A read/write instruction signal 6 that instructs the magnetic storage device 1 to read or write, and an index signal 7 that outputs a pulse every rotation of the storage medium are input to the gate circuit 2; The index signal 7 is outputted to the count input signal 8 of the counter 3 only while the read/write instruction signal 6 is outputted. The power source 10 of the counter 3 is supplied from the battery 5, so that the counted value can be stored even when the power of the entire information processing device is turned off. Counting result 9 of counter 3
is compared with the number of rotations requiring maintenance by a maintenance required rotation number comparator 4, and if the counted result 9 is large, a warning signal 11 is output to warn the user of the necessity of maintenance. After the user performs maintenance, the reset signal 12 for the counter 3 is inputted to initialize the counter 3 in preparation for the next warning generation.
