Abstract
A disk drive apparatus includes a shutter operating pin engageable with a pin receptacle on the shutter of a disk cartridge. The shutter operating pin is carried by a shutter operating arm which is pivotable for causing a transverse shift of the shutter operating pin for shifting the shutter from a closed position, at which a disk is inaccessible, to an open position, at which the disk is accessible. An arm lock mechanism is provided for locking the shutter operating arm at the shutter fully opened position. The arm lock mechanism is provided in the cartridge holder. The cartridge holder is also provided with a cartridge lock mechanism which includes a cartridge lock pin engageable with a lock pin receptacle on the disk cartridge. The cartridge lock mechanism is actuated by means of the shutter operating arm at the shutter fully opened position, to establish locking engagement of the cartridge lock pin with the lock pin receptacle of the disk cartridge.
