ABSTRACT:
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.
