Abstract:
A method of making a magnetic write head that has an air bearing surface (ABS) comprising the steps of:forming a first pole piece with a first component wherein the first component has a first surface;forming a forming structure on a first region of the first surface of the first component wherein the forming structure has a first surface and a forming wall;forming the first pole piece with a second component that has horizontal and vertical portions, the horizontal portion being formed on a second region of the first surface of the first component and the vertical portion being formed abutting the forming wall wherein the vertical portion has a first surface and first and second edges that define a tack width of the head at the ABS;forming a forming layer on the horizontal portion, adjacent the first edge of the vertical portion, wherein the forming layer has a first surface;forming the first surface of the vertical portion and portions of the first surfaces of the forming structure and the forming layer into a first recess with the first surface of the vertical portion forming a surface of the first recess;forming a write gap layer in said first recess, the write gap layer defining a second recess; andforming a second pole piece in the second recess with first and second edges that define a second pole piece width at the ABS.
