ABSTRACT:
A removable disk cartridge for use with a rotary actuated disk drive includes an enclosure having a top, a bottom, and a side connecting the top and bottom. The enclosure has a cutout formed by removal of a portion of the top, removal of a facing portion of the bottom, and removal of a portion of the side connecting the removed top and bottom portions. A disk is mounted for rotation inside the enclosure. The disk is exposed at a top surface, a bottom surface, and an edge. A door is pivotally mounted on the enclosure. The door has a top surface to shield the top surface of the disk, a lower surface to shield the bottom surface of the disk, and a side surface to shield the edge of the disk. The door has a closed position to fully seal the cutout, and the door has an open position to fully expose the cutout. Access to the top surface, bottom surface, and edge of the disk is provided by the exposed cutout.
