Abstract:
A method of making a magnetic write head, comprising:forming a first component of a first pole piece with a photoresist layer having an opening;frame plating a second component of the first pole piece in the opening on the first component while leaving a remainder opening portion that exposes a top surface of the second component wherein the second component defines a track width of the write head;soft baking the photoresist layer until the remainder opening portion has sloping side edges;plating a sacrificial layer in the remainder opening portion on the top surface of the second component, wherein the sacrificial layer has a top surface;removing the photoresist layer;forming a forming layer adjacent the second component and the sacrificial layer, wherein the forming layer has a top surface;lapping the top surfaces of the forming and sacrificial layers until they are flush;removing the sacrificial layer while leaving the remainder opening portion;forming a write gap layer in the remainder opening portion on the top surface of the second component; andplating a second pole piece layer in the remainder opening portion on top of the write gap layer.
