Abstract
A disk cartridge, for use in a disk drive, has a shutter for opening and closing over a disk access opening. A compression spring provides a force to bias the shutter to a closed position. The spring is coupled at one end to the shutter and follows an arcuate path substantially concentric with the disk within the cartridge.
