ABSTRACT:
An engagement interface between a removable cartridge containing a rigid disk for storage of data and a disk drive. The cartridge includes an opening for a hub of the disk for spinning and the disk drive has a magnetic spindle with connecting mechanism for extending the spindle into contact with the hub and retracting it out of contact. The cartridge also includes a disk immobilizer to hold the disk with its hub centered in the opening when the cartridge is outside the disk drive, and a detachable mechanical interconnection between the hub and the housing to retain the hub generally centered in the opening when the disk immobilizer is deactivated as the cartridge is inserted in the disk drive but before the spindle has engaged the hub for instances when the cartridge is inserted in the disk drive with other than a vertical orientation.
