ABSTRACT:
A filter system for a hard disk drive that complies with the PCMCIA specifications. The disk drive includes a cover that is coupled to a base plate by a spring clamp. The cover and base plate encapsulate a disk and accompanying actuator arm assembly in an area referred to as the HDA. Located between the HDA and the spring clamp is a carbon filled breather filter which removes contaminants such as particles and acidic gases from air that flows through the cover and base plate interface. The disk drive also has a pair of recirculation filters which capture any particles or acidic gases within the HDA.
