Abstract In a magnetic recording system wherein the transducing head is carried by a pad suspended adjacent the moving recording medium by a spring gimbal or other device weakly restraining pad motion with respect to the head arm parallel to the recording surface, and a cantilever spring arm loading the pad so as to force it to the proper flying height from the recording medium, apparatus for preventing the pad from being shifted parallel to the recording surface because of friction between the pad and the spring arm as the pad rides up and down on deviations from the position of the moving recording medium immediately beneath the head. The apparatus comprises a rotatably attached intermediate arm carrying a thin resilient strip, said strip being interposed on edge between the cantilevered spring arm and the pad. As the pad moves up and down, deflecting the spring, the strip twists and isolates the pad from the forces parallel to the recording surface and along the spring arm, generated by the spring arm.
In data transcribing apparatus comprising a head pad carrying a transducing head and having a load point opposite its flying surface at which force counteracting hydrodynamic lift is applied, a pad support arm, a pad mounting element attaching the pad to the support arm and weakly restricting the head to motion along a preselected straight line approximately normal to the flying surface, and a spring loaded head loading arm rotatably attached to the support arm and extending adjacent the load point, improved apparatus for transferring the head loading arm force to the load point without application of force to the head causing deviation from said straight line head motion, comprising an intermediate arm rotatably attached to the support arm and a resilient strip interposed on edge between the head loading arm and the load point and attached at its ends to the intermediate arm, the middle portion of the strip deflecting torsionally with respect to its ends as the head translates along said straight line.
