Abstract
A disk cartridge has a passive shutter opening mechanism. The cartridge is adapted so that during insertion into a drive, the shutter is automatically opened. A projection is coupled to a shutter surface. The projection is sized so that it impinges on the front of the drive as the cartridge is inserted. This impingement causes the shutter to open and no levers are required to activate the shutter. The shutter also has a latch that operates to keep the shutter in the closed position. As the cartridge is inserted into the drive, the latch impinges on the drive opening causing the latch to release the shutter.
