Abstract
A disk cartridge has a rotary inner shell, or shutter, to permit access to a data-storage medium disposed within the shell. A driving-access opening is located in a bottom surface of the cartridge's outer shell to allow a drive mechanism to rotate the storage medium. A portion of the inner shell projects into the driving-access opening to aid in the rotational alignment of the shell. The outer shell has a wedge-shaped disk-access opening. The inner shell rotates over a predefined arc to expose the data storage medium via the disk-access opening. A liner is disposed between the inner and outer shells to reduce sliding friction between the shells.
