A lapping carrier for machining a row of magneto-resistive elements, comprising a plurality of movable elements, the movable elements terminating at an outer surface to form a generally planar mounting surface for a row of magneto-resistive elements, wherein the lapping carrier comprises a ceramic material, the ceramic material comprising an electrostatic discharge dissipative material having a density of a least 95% of theoretical density.
A method for lapping a row of magneto-resistive elements, comprising
- mounting a row of a magneto-resistive elements to a lapping carrier, the lapping carrier comprising plurality of movable elements, the movable elements terminating at an outer surface to form a generally planar mounting surface for a row of magneto-resistive elements, wherein the lapping carrier comprises a ceramic material, the ceramic material comprising an electrostatic discharge dissipative material, and wherein there is at least one movable element for three magneto-resistive elements so at to provide at least a 1:3 ratio of movable elements:magneto-resisitive elements;
- and
- machining the row to remove material from the row.
A lapping carrier assembly, comprising:
- a lapping carrier for machining a row of magneto-resistive elements, comprising a plurality of movable elements, the movable elements terminating at an outer surface to form a generally planar mounting surface for a row of magneto-resistive elements, wherein the lapping carrier comprises a ceramic material, the ceramic material comprising an electrostatic discharge dissipative material having a density of a least 95% of theoretical density;
- an actuator assembly including a plurality of transducers for biasing a plurality of respective movable elements.
