Abstract
A disc drive includes a housing enclosing a spindle motor that is able to spin a disc. A filter within the housing is positioned so that a filter stream of moving gas created by a spinning motion of the disc flows through the filter. Additionally, a flow divider is secured to a portion of the housing and positioned within the filter stream upstream of the filter, splitting the filter stream into a first branch and a second branch. Both branches flow through the filter.
Claims28
A disc drive comprising:
- a housing enclosing a spindle motor operable to spin a disc;
- a filter within the housing positioned so that a filter stream of moving gas created by a spinning motion of the disc flows through the filter;
- and
- a flow divider secured to a portion of the housing and positioned within the filter stream upstream of the filter, splitting the filter stream into a first branch and a second branch, both flowing through the filter.

A disc drive comprising:
- a housing comprising a base and a top cover secured to the base, the housing enclosing a spindle motor spinning a disc;
- a filter within the housing adjacent the disc, the filter positioned so that a gaseous filter stream created by the spinning disc flows through the filter;
- and
- a first vane secured to a portion of the housing and positioned within the filter stream upstream of the filter, the first vane splitting the filter stream into a first branch and a second branch, both flowing through the filter, wherein a first flow rate of the first branch is substantially the same as a second flow rate of the second branch.

A disc drive comprising:
- a housing enclosing a spindle motor spinning a disc and a filter adjacent the disc, the filter positioned so that a gaseous filter stream created by the spinning disc flows through the filter;
- and
- means for minimizing turbulence in the filter stream upstream of and adjacent to the filter.
