Abstract
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.
