Abstract: A process for lapping a row of head sliders involves fixing the row to a lapping tool fixture, actuating each of multiple force pins to set each head slider for lapping to a respective target wedge angle, and simultaneously lapping accordingly. Each target wedge angle may be achieved by applying a respective torque to a compliant elastomer between each force pin and corresponding head slider, to transfer a pressure gradient corresponding to the torque to the corresponding head slider. Such torques may be applied through at least two wedge angle flexures interconnecting a rotatable box structure and a fixed back wall of a lapping tool, wherein the flexures virtually intersect at and define an axis of rotation about which the torques are applied. The process may further involve actuating each force pin to set each head slider for lapping to a respective reader target stripe height, and simultaneously lapping accordingly.
