ABSTRACT:
A floppy disk has a magnetic disk (1) accommodated in a casing provided with a head insertion opening. When cleaning the floppy disk, air in the casing is sucked through the head insertion opening while the magnetic disk is rotated and ionized air is blown toward the disk surface through the head insertion opening. An ionizing needle (13) ionizes the air before it hits the disc (1). Suction nozzles (12a and 12b) suck air away from the disc.
