Abstract
An engagement interface between a removable cartridge containing a rigid disk for storage of data and a disk drive that maintains the disk immobilized during insertion into the disk drive so that the drive can be oriented in any direction with respect to gravity. 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 an overcenter disk immobilizer to hold the disk with its hub centered in the opening when the cartridge is outside the disk drive and to release the disk when the cartridge is within the disk drive and the hub is engaging the spindle.
