  • Disc cartridge with opposing sets of crossed ribs directly pressing wiping members into contact with both sides of disc
    Patent number: 5619391
    Abstract: A magnetic disc cartridge includes two sets of opposing ribs arranged on opposite sides of the cartridge so that each rib of one set of ribs is skew with respect to each rib of the other set of ribs. The ribs exert pressure on both sides of a rotating medium via wiper elements, which sandwich the medium, so as to clean debris from both sides of the medium while maintaining medium planarity in a region defined between the two sets of opposing ribs. Optionally, each rib of the one set of ribs may cross perpendicularly with respect to each rib of the other of the sets of ribs.
