摘要:
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.
