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.

A disk cartridge has two shell layers. The first layer encases the disk medium. The second layer encases the first layer. Both layers have a head access opening such that rotation of one layer relative to the other layer causes the head access openings to be aligned or misaligned. When the head access openings are misaligned the cartridge is closed. When the head access openings are aligned the cartridge is open.

A disk cartridge has a rotary shutter, a flat nose portion, and a lever retraction area. The cartridge is adapted for use in a drive having a lever for opening a rotary shutter. The shutter lever grabs the lever and rotates it counter-clockwise. The cartridge has a flat nose portion to provide a shutter arm alignment surface during shutter opening in conjunction with the lever and a cut-out portion in the bottom of the cartridge to allow the lever to retract the shutter further into the cartridge.
