ABSTRACT:
A filtering apparatus and associated method for recirculating fluid in a data storage device. The filtering apparatus comprises a fluid flow guiding member and a filter. The fluid flow guiding member comprises a shroud disposable substantially transverse to the disc comprising an arcuate surface in a closely mating relationship with the disc edge. The fluid flow guiding member further comprises a recessed surface disposable radially outwardly from the disc and cooperatively with the shroud defining a fluid passageway. First edges in the shroud define an inlet to the passageway, and second edges in the shroud define an outlet from the passageway. The filtering apparatus further comprises a filter that is supportable by the fluid flow guiding member within the passageway. The filter provides a curved member against which the fluid flow first impingingly engages upon entering the passageway, thereby being guided by the curved filter toward the outlet. In some embodiments the fluid flow guiding member is formed by a portion of the enclosure base structure; alternatively, the fluid flow guiding member can be a component attached to the enclosure base.
