ABSTRACT:
A base support member for a disc drive is provided. The base support member includes a disc support cavity configured to house and support a spinning disc, and a filter support cavity configured to house and support a filter. The base support member also includes at least one surface that defines an airborne filtering channel that is generally disposed within the filter support cavity of the base support member. The airborne filtering channel has an inlet opening positioned in a first location proximate the disc support cavity and an outlet opening positioned in a second location proximate the disc support cavity. The airborne filtering channel is configured to receive a flow of air from the spinning disc at the inlet opening, pass the flow of air through the filter cavity and to discharge the flow of air at the outlet opening.
