Abstract

PURPOSE:To remove the damage due to dust for the floating head and magnetic disc, by avoiding the mixture of outer air in the schraud at all times, through the additional provision of sub-blower which is of small size and low in power consumption. CONSTITUTION:At the operation of the main blower 1, the air removing dust by the filter 4 flows in the shroud 5, it passes through the surrounding of the disc 6 and the positioner 7, and it is discharged from the exhaust 8. Next, when the disc 6 stops revolution, the selection valve 3 is operated, the flow path from the main blower 1 is shut, the path from the sub-blower 2 is open, and the sub-blower 2 is simultaneously run. Thus, the air pressure in the shroud 5 is increased by a slight amount against external air to avoid the invasion of external air from fine clearance of the joint of the shroud 5 and the bearing.
