ABSTRACT:
A disk cartridge for a disk drive has a slide door normally biased to the closed position. A recess on the door is positioned laterally offset from the horizontal center as to be oriented in either the upper or lower portion of the door depending on the orientation of the cartridge housing. The recess is engagable by a door opening mechanism on the disk drive to move the door to its open position wherein the disk media is exposed to the sensors in the disk drive. The recess is engagable by the door opening mechanism regardless of the orientation of the cartridge. A lock button supported on a resilient support engages the door recess when the door is in its closed position to thereby lock the door; the door opening mechanism engaging the lock button to unlock the door when engaging the recess.
