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.
