力の供給を中１１−４る。First, when the power supply switch 11 of the battery-driven magnetic recording device 7 is turned on, the head 3 moves from star 1 to position 1 of the access operation, and as shown in step 21 in FIG. reset 1
~ will be done. Next, the magnetic disk is inserted into a predetermined location, but since the magnetic disk motor 1 remains stopped until access is received from the host device 13, the magnetic disk does not start rotating. Here, when access is started from the host controller 13, the magnetic disk motor 1 is driven and the magnetic disk starts rotating. Then, in step 22, when the battery 8 of the power source is exhausted and its terminal voltage has decreased below the base I%j voltage of the battery 9, the 7I battery depletion fg signal is output to 1 and held. If it does not exist, the process advances to the upload 23 to read the data on the magnetic disk, and it is determined whether or not there is an η-read access from the host device 13. Lead's Aku 1 here?
If there is a disk, proceed to the screen 24 and drive the head 3 to read data from the magnetic disk. Next, the process advances to step 25, where it is determined whether or not reading of the f-tater has been completed.If it has not been completed, the process goes to step 24 again to continue reading the data. On the other hand, if the reading of data has been completed, the process advances to step 26, and it is determined whether there is an access from the host device 13 for writing data to the magnetic disk. Further, if there is no read access in step 23, the process directly advances to step 26. Here, it is determined whether or not there is an access from the host device 13 to the host device 13 for writing data to the magnetic disk. If there is a write access, the process advances to the next step 27 and the host 1 is transferred to the magnetic disk. Equipment 13
Write down the dates from. Next, the process proceeds to step 28, where it is determined whether or not the loading of the data into the magnetic disk is completed.If it is not completed, the process proceeds to step 27 again. Continuing to add data. On the other hand, after completing the data reading, the user goes back to the screen 22 and checks the voltage of the battery 8. Further, if the access to the line I~ is successful in step 2G, the process directly goes to step 22. On the other hand, the platform where the battery depletion signal is present in step 22 (step 2
9, the excitation current is applied to the solenoid of the power switch 11, and the power switch 11 is turned off, thereby stopping the supply of power from the battery 8.

Due to L wear, the power supply voltage value drops below the minimum allowable power supply voltage value for each component of the battery-driven magnetic recording device, such as the CI suspension section and the magnetic disk motor.
, Wow, the motor for rotating the magnetic disk is rotating unevenly.
When the possibility arises without adversely affecting the rotation of the magnetic f-isk, access from small devices is prohibited. Therefore, it is possible to reliably prevent errors caused by uneven rotation of the magnetic disk during writing of data to the magnetic disk and reading of data from the magnetic disk. In addition, since access from the host device is prohibited after a series of accesses from the host device have been completed, data read and write operations (1-7J interrupted, ie IJ
