Abstract
A pressurized seal which comprises the interface between a disk drive spindle housing and a disk cartridge housing whereby dirty, unfiltered air is prevented from entering the disk area of the cartridge when mounted on the disk drive. The seal is comprised of an annular stop having three channels. An inner channel has mounted therein a circular cross-sectioned, flexible tube running the length of the channel. A intermediate channel connects to a source of pressurized filtered air. An outer ring mounts a flap seal which is forced against the cartridge housing by the pressurized filtered air.
