Abstract
A plenum assembly for use in a data storage device to direct and filter recirculating currents established by high speed rotation of a recording disc. The plenum assembly includes a top plate and a partitioning wall which projects from the top plate to form opposing, longitudinally extending first and second chambers. A first portion of the recirculating currents is directed along the first chamber and a separate, second portion of the recirculating currents is directed along the second chamber. A recirculation filter transversely extends across the first and second chambers and intersects the partitioning wall so that the respective first and second portions of the recirculating currents concurrently pass through adjacent sides of the recirculation filter before exiting the plenum assembly and merging into a combined set of recirculating currents.
