Abstract: A disk drive (50) having an integral apparatus (280) for ensuring that the door (68) of a removable cartridge (52) is properly opened, that the heads (286) of the disk drive (50) are properly unloaded onto the disk (256) in the cartridge (52) and that air filters (296) are appropriately positioned. The integral apparatus (280) includes an integral member (300) which provides a door safety stop (302) for ensuring that the door (68) of the cartridge (52) is properly opened should the door position reach a predefined threshold, and for preventing the further reception of the cartridge (52) into the disk drive (50) should the door position not reach the predefined threshold. The integral apparatus (280) further includes a ramp device (304) for receiving the actuator arm (282) onto which a head (286) is fixed and for unloading the head (286) onto the disk (256) and a base (294) for holding an air filter (296) relative to the door safety stop (302) and the ramp device (304) apparatus.
