Abstract
A lapping mount tool and a process for lapping a row of head sliders involves affixing the row to a lapping mount tool fixture, actuating each of multiple first actuation pins to set each head slider for lapping to a respective element target stripe height, and simultaneously lapping accordingly. The process may further involve actuating each of multiple second actuation 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 angular force to a compliant elastomer adhered to the fixture and to the row, where such angular forces may be applied through at least two flexures interconnecting a rotatable first structural member and a second structural member of the lapping mount tool, wherein the flexures virtually intersect at and define an axis of rotation about which the angular forces are applied.
