Abstract
PURPOSE: To prevent a magnetic head, a disk and a housing from being damaged, by providing a valve for blowing off air being in a disk chamber or making air flow in through a filter, by a difference between internal pressure and external pressure of the enclosed disk chamber.
CONSTITUTION: In a disk housing 1 consisting of an enclosed structure, a magnetic disk 7 whose rotation is driven, a head 5 supported by a head bar 6, a pressure control valve 4, and a moisture absorbing agent 3 for absorbing moisture and corrosive gas in a disk chamber 2, etc. are provided. As for the pressure control valve 4, when internal pressure becomes high, force pushing up a valve 10 by internal pressure becomes larger than external pressure by the left valve and a spring 12, and internal air flows out to the outside through small holes 13 and 14. When internal pressure becomes low, the right valve operates in the same way, and air goes into the disk chamber 2 through a filter 18 for filtering dust and a moisture absorbing agent 17. In this way, damage of the internal device and the housing is prevented.
