Abstract
An apparatus for loading and unloading a magnetic head assembly on a magnetic recording surface which permits separation of function between load/retract and flying and which produces a predictable pitch to the magnetic head assembly in the static condition and no pitch bias in the dynamic flying condition. The present invention improves on the IBM type 3370 by adding to the single piece spring/load beam element a pair of wings which extend laterally on each side thereof and a pair of stationary cam members positioned on opposite sides of the element. The arrangement of the torque wings and cams permits unrestricted retraction of the slider. The placement of the wings results in a favorable ratio of lift point to load beam bending point and more control of load zone accuracy.
