ABSTRACT:
Apparatus for supporting a magnetic head assembly adjacent a recording surface and for loading and retracting the head assembly. The apparatus comprises a rigid, cantilevered support arm; a thin, resilient, gimbal sheet attached to the free end of the support arm; a magnetic head assembly including a tranducing element carried by the gimbal sheet; a lift bail mounted on the head assembly; a spring-loaded force arm rotatably attached to the support arm for applying a force to the head assembly on the side thereof opposite to the transducing side thereof; a lifting finger attached to the force arm at the point where the force arm engages the head assembly, the lifting finger extending into but not engaging the lift bail when the force arm is engaging the head assembly; a pivot arm for engaging the force arm and for moving the force arm out of contact with the head assembly, the lifting finger engaging the lift bail when the force arm is moved for retracting the head assembly from the recording surface; and a centrally mounted actuator arm including a caming surface for operating the pivot arm when the support arm is retracted so as to provide for a symmetrical lift force in a space saving design.
