A data storage tape cartridge used in a tape transport apparatus that
incorporates air bearing technology is provided. The tape cartridge
includes a housing for storing the data storage tape and a compressible
filter. The filter is located proximate to an opening, or air inlet, that
is in communication with the housing interior. The housing may also have
a second opening, or air outlet, in communication with the housing
interior such that the filter is interposed between the inlet and the
outlet. Further, the housing may include a storage region to retain the
filter in the compressed state. The filter and the storage region may
have congruent geometries. A method of supplying filtered air to a tape
transport apparatus is also provided. The method contemplates drawing
ambient air through the filter and passing it directly through the outlet
opening for use by the tape transport apparatus.
