Abstract
An anti-rattle mechanism for a disk cartridge addressing the problems of particulate generation which occur in disk cartridges when a disk assembly moves around inside the cartridge contacting the cartridge walls. The anti-rattle mechanism includes an anti-rattle ring which is movable by a cam surface between a clamping position and a released position. When the disk cartridge is outside of a disk drive, the anti-rattle mechanism is in a clamping position to completely or partially captivate the disk assembly within the cartridge. As the disk cartridge is inserted into the disk drive, the anti-rattle mechanism moves to a released configuration where a disk is freely rotatable within the cartridge. The anti-rattle mechanism is moved between the clamping position and the released position by rotation of a movable door.
