Abstract
A ventilation and filtration system and method for an enclosure isolating a memory device spinning disk mechanism from airborne contaminants in which a vent through a remote filter from the ambient atmosphere is positioned with one opening adjacent the center portion of the spinning disk whereby the enclosure is vented through the filter to the ambient pressure at a location at substantially the lowest pressure within the enclosure as a result of the air pumping action of the spinning disk to thereby over pressurize the remainder of the enclosure and minimize unfiltered leaks of outside air into the enclosure.
