Abstract
PURPOSE: To perform stable reading and writing operation by permitting a head to float ver a disk plat uniformly at its inner and outer circumferential parts, by increasing the velocity of air flow gradually from the outer circumferential part to the inner circumferential part.
CONSTITUTION: An air flow mechanism 14 which supplies an air flow 16 variable in velocity between a disk plate 1 and a magnetic head 2 is coupled with a housing 13. This air flow mechanism 14 has air supply holes 19 different in diameter from a duct 15, and air is supplied by a pump 18 through a pipe 17. The air supply holes 19 has greater diameters at the outer circumferential part of the disk plate 1 and less diameters at the inner circumferential part. The air supply holes 19 having less diameters are arranged close to the pump 18 to prevent the loss of the quantity of flow.
