Abstract
A giant magnetoresistance recording head includes a writer having a top pole, a shared pole, a conductive coil and a write gap region. The top pole includes a first top pole piece and a second top pole piece. The second top pole piece is formed at least in part over the first top pole piece and is recessed from the air bearing surface. The first top pole piece is formed over a top flat surface of the shared pole and is separated from the shared pole by the write gap region. The shared pole has a recess on the top surface. The recess is placed under the top pole and filled with a non-magnetic material. The non-magnetic recess in the shared pole defines the throat height of the writer.
