Abstract
The invention presents a magnetic recording disc cartridge with two small fabric liners affixed inside the media compartment. One liner covers the lifter and the other covers the raised structure. The lifter and the raised structure bring the liners in contact with the flexible surface of the disc as it rotates, thus cleaning the disc. One or more protrusions in the media compartment prevent the disc from abrading the surface of the media compartment.
