Abstract
An improved magnetic read/write head-positioning apparatus including a cantilevered lead screw head carriage-driving mechanism and a damping assembly for damping any transverse motion of the unsupported end of the lead screw. The damping assembly includes a leaf spring having one end affixed to the supporting frame and the other end positioned opposite the unsupported end of the lead screw, and a slider button disposed between the leaf spring and the unsupported lead screw end and carried by the lead screw so as to frictionally engage the leaf spring and cause a force to be exerted on the unsupported lead screw end tending to resist any transverse motion thereof.
