Abstract
A magnetic recording disk cartridge has a write control sensing aperture extending through the cartridge. A shutter is mounted within the cartridge for back and forth rotational movement between aperture blocking and aperture opening positions. The shutter is restrained against accidental movement or drift from these positions. The shutter can be assembled locked in a write protect position and must be reassembled to permit movement between the write protect and write enable positions.
