Abstract
A removable cartridge for a disk drive where the cartridge has a housing, a disk contained within the housing and a mechanism for reducing the rattling of the disk when the cartridge is not inside the disk drive and for permitting the free rotation of the disk when the cartridge is inside the disk drive. The rattle-reduction mechanism includes an inclined surface defined in the housing and a member having a first portion and a second portion. The interaction between the second portion of the member and the inclined surface of the housing may cause the first portion of the member to move into and out of contact with the hub. The contact between the first portion and the hub reduces the tendency of the disk to rattle. In one example embodiment, the cartridge has a housing with cartridge nut threads and a cartridge screw with cartridge screw threads. In this embodiment, interaction between the cartridge nut and the cartridge screw threads may cause a portion of the cartridge screw to move into and out of contact with a flange of the hub. A structure in the disk drive causes the cartridge screw to rotate in a manner such that the interaction between the cartridge screw threads and cartridge nut threads causes the cartridge screw to move away from and no longer contact the hub.
