Abstract
Devices, systems, and methods prevent rigid recording media for video and other data from rattling within a cartridge when that cartridge is removed from a disk drive. To decrease rattling (and the resulting damage to the disk), a hub of the disk is urged against an inner surface of the cartridge housing. A door translates laterally to provide access to the disk within the cartridge. A feature is defined by an inner surface of the cartridge housing, and one or more resilient arms extend from the door assembly so as to engage the feature when the door moves towards a closed position. The feature deflects the arm axially against the disk, so that the arm can act as both an actuation mechanism and a biasing spring.
