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 and first and second edges that define a width W1 at the ABS;forming the first pole piece with a second component on a portion of the first surface of the first component wherein the second component has a first surface and first and second edges that define a track width W2 of the head at the ABS;forming a forming layer on another portion of the first surface of the first component, adjacent the first and second edges of the second component, wherein the forming layer has a first surface;forming the first surface of the second component and portions of the first surface of the forming layer into a first recess with the first surface of the second component forming a bottom surface of the first recess;forming a write gap layer in said first recess wherein the write gap has a second recess; andforming said second pole piece component in the second recess of the write gap layer with first and second edges that define a width W3 at the ABS.
