Abstract

An interface between a removable cartridge containing a rigid disk for storage of data and a disk drive. The cartridge includes a normally closed and locked pivoting arcuately shaped shutter to cover a disk access window and an opening for a hub of the disk for spinning. The disk drive includes a shutter opener arm for unlocking and opening the shutter as the cartridge is inserted therein, a magnetic spindle with connecting mechanism for extending the spindle into contact with the hub and retracting it out of contact, and an abutment surface to deactivate a disk immobilizer when the cartridge is inserted into the disk drive.
