摘要

A generally square disk cartridge (3) for a recording disk (4) includes at least one air filter (10) in a corner (9) of the cartridge (3) and a circular rib (13) adjacent the disk (4) and between the disk (4) and filter (10). The cartridge (3) may also include a radial rib (12) connected to the circular rib (13) to enhance air flow to the filter (10). Air filters (10) may be located in each of the corners (9) of the cartridge (3) with associated circular (13) and radial (12) ribs to induce air flow to each.
