Abstract: An improved magnetic head carriage and support apparatus including a carriage body a lower head supporting arm affixed to the carriage body and carrying a gimbaled mounted lower head, an upper arm pivotally connected to the carriage body and movable between a retracted position and a media engaging position in which a stop is engaged. The upper arm carries an upper head that is also gimbal mounted and head load is applied by a light weight flexure spring such that when the upper arm is in the media engaging position the head are free to move relative to the supporting arms as either the media moves out of it mid-plane or the carriage moves towards or away from the media mid-plane.

Abstract: An improved disk drive and centering mechanism for attachment to the spindle of a microfloppy drive, including a first circular segmented plate attached to a second circular segmented plate by four parallel spring wires. The first plate is fixedly attached to the drive spindle and the second plate is resiliently carried by the four spring wires. A drive pin is carried by the second plate, and the four parallel wires limit the motion of the drive pin and the second plate to vertical and horizontal displacement relative to the first plate and thereby prevent any tilting of the vertical axis of the drive pin.
