Abstract
A cartridge for a floppy diskette has a cover shell and a back shell. Fabric liners are provided on the interior of the cartridge so that the floppy diskette is cleaned when it rotates. A lifter is provided on the back shell underneath the fabric liner. A raised region is formed on the inner surface of the cover shell under the fabric liner and opposite the lifter on the back shell. The raised region rises from the plane of the cartridge shell beginning at the periphery and rising until a central raised area is reached. The angle of inclination, .alpha., is less than 20.degree.. This minimizes the likelihood that the raised region will cause an imprint on the floppy diskette, thereby damaging it, if the cover and back shells of the cartridge are squeezed together.
