Abstract:
A disk cartridge comprising:a disk cartridge housing including an upper cartridge housing and a lower cartridge housing;a disk assembly positioned within the disk cartridge housing and including a ta storage disk and a hub, the disk assembly having an axis of rotation;an opening in the disk cartridge housing providing access of a read/write head to the data storage disk;a door movable between a closed position in which the door covers the opening and an opened position;an anti-rattle mechanism movable in a direction parallel to the axis of rotation of the disk assembly between a clamping position in which motion of the disk assembly within the housing is prevented and a released position in which the disk assembly is freely rotatable within the disk cartridge housing, wherein when the anti-rattle mechanism is in the clamping position the disk assembly is clamped against the disk cartridge housing causing outward deformation of the housing; andwherein the anti-rattle mechanism includes a non-rotatable anti-rattle ring surrounding a rotatable hub of the door, the anti-rattle ring and the rotatable hub forming a cam surface and a follower such that rotation of the door causes axial motion of the anti-rattle ring.
