Abstract
A giant magneto-resistive head is provided which includes a novel high data-rate stitched pole inductive magnetic write head. The write head incorporates a non-magnetic spacer layer and a magnetic pole yoke that is recessed from the magnetic pole tip. The spacer layer shortens the throat height of the write head, reduces its saturation write current, and improves its overwrite and side erasure performance.
