Abstract
Method and apparatus for protecting a data storage device from fluid-borne contaminants. The device includes a housing in which a rotatable disc is disposed. The housing is formed from first and second rigid housing members. The first housing member is provided with an exterior filter support surface, an opposing interior surface and at least one filter access aperture. A contaminant adsorbent filter is placed on the exterior filter support surface, and a seal is applied to the first housing member to encapsulate the filter. During subsequent rotation of the disc, fluidic currents pass across the interior surface, through the at least one filter access aperture and to the adsorbent filter. Preferably, the filter is installed after the first and second housing members are mated. The filter support surface is preferably formed as part of a recess in the first housing member which projects into the housing.
