Abstract: Magnetic write heads and corresponding fabrication methods for bi-layer wrap around shields resulting in dissimilar shield layer widths are disclosed. A gap structure is formed around a main write pole for a magnetic write head. A wrap around shield for the main write pole is fabricated to include a first magnetic layer proximate to the main write pole and a second magnetic layer on the first magnetic layer. A width of the first magnetic layer is less than the width of the second magnetic layer, and back edges of the first and second magnetic layers are coplanar. Further, a throat height of the wrap around shield is maintained between the first and the second magnetic layers because their back edges are coplanar.

Abstract: Methods of fabricating magnetic write heads and electrical lapping guides (ELG's) using a split gap deposition process is described. A removal process is performed on a magnetic material to define a main write pole and to define a corresponding ELG for the main write pole. A first non-magnetic gap layer is deposited. A mask and liftoff process is performed to deposit an electrically conductive material on the first gap layer disposed along a front edge of the ELG. A second non-magnetic gap layer is then deposited and a shield is fabricated for the write pole.
