Floppy disk drive apparatus
摘要:
A floppy disk drive apparatus includes an index hole sensor, a spindle for holding a floppy disk, and a motor for rotating the spindle. The index hole sensor generates a high-level signal when the floppy disk is set on the spindle. The floppy disk drive apparatus is provided with a motor drive circuit which drives the motor in response to the high-level signal from the index hole sensor.
