ABSTRACT:
A fluid guide for recirculating fluid through a filter in a data storage device, the data storage device having a disc rotatably supported on a base and operatively imparting a velocity to the fluid surrounding the disc resulting in a generally outwardly spiraling fluid flow. The fluid guide comprises a shroud supportable by the base substantially transversely to the disc comprising a distal surface closely matingly engageable with the disc edge, a vane extending from the shroud substantially parallel to the disc and opposing the base, the vane comprising a leading edge disposed transverse to the disc and within the fluid flow, guiding the fluid toward a proximal end of the shroud beyond the disc edge; and a retaining feature adjacent the shroud proximal end adapted for retaining the filter. Two or more fluid guides are stackable and fixable to the base to interlace the vanes between adjacent discs in a multi-disc stack. Methods of populating and depopulating the data storage device are possible by alternatively placing the discs and the guides.
