The present invention relates to an air guide for use in a disc drive such that
air flow can be redirected to improve the efficiency of a filter located within
the disc drive. Embodiments of the present invention provide for an air guide having
air guide surfaces that, in conjunction with sides of the disc drive housing, are
configured to channel air flow off a spinning disc, through a filter, and back
into the mainstream air flow. The air guide may be formed as an integral unit with
either the inner major surface of the cover or of the baseplate, or both, such
that the air guide may extend over part of the disc surface and provide an effective
channel for air flow without the need for additional assembly processes during manufacture.
