ABSTRACT:
In a magnetic disk storage system incorporated in a removable, portable module for use in a microcomputer system, a hinged separator element having a plurality of angled surfaces is movable between first and second positions. In the first position, the disk storage system is in an operational state with magnetic transducers loaded onto the surfaces of rigid magnetic disks and a carriage which mounts cantilevered beams for the transducers being free to move radially relative to the disks. In the second position, carriage motion is inhibited by the separator element which engages the cantilevered beams to raise the transducers away from the surfaces of the disks and into unloaded positions. A spring loaded trigger member which normally engages the separator element to latch the separator element in either of the first and second positions is momentarily disengaged from the separator element to permit movement of the separator element from the first to the second position by the spring or from the second to the first positions in response to movement of the carriage.
