ABSTRACT:
A non-rotational, air filtering, head cleaning, and head cushioning device for a disk drive comprising a member and rigid support structure adapted to allow insertion of the device into a disk drive. The member, preferably comprising urethane-impregnated felt cloth, has a central aperture to avoid contact with a drive spindle of the disk drive when seated within the disk drive. When left in the disk drive, the device filters air entering the drive, cleans the heads whenever the drive checks if a disk is present, and cushions the heads whenever the drive is moved.
