Abstract:
In combination, a filter assembly for a disk drive, said combination comprising:a disk drive including a drive housing, and means mounted in said drive housing for storing data; a filter assembly including a tubular housing and an opening formed at a distal end portion of said tubular housing, said housing mounted in the disk drive, said tubular housing defining an interior space; a first chemical filter disposed within said interior space, said first filter for adsorbing vapors; a second filter disposed at the end portion of the tubular housing, proximate the opening; said second filter extending outwardly of the tubular housing and defining a pocket outside of the tubular housing for receiving gases that flow within the disk drive such that a portion of said gases are also exposed to said first filter; and a hole formed in said tubular housing, said hole interconnecting the environment surrounding the disk drive and the interior space thereby allowing environmental gases to enter and escape the disk housing through said filter assembly in response to pressure changes within the disk drive.
