Abstract:
1. A method of fabricating a magnetic write head, the method comprising: depositing magnetic material; forming a first mask structure on the magnetic material that defines a shape for a main write pole and a corresponding electrical lapping guide (ELG) having a front edge; performing a removal process which removes the magnetic material exposed by the first mask structure to define the main write pole and the ELG having the front edge; removing the first mask structure; depositing a first non-magnetic gap layer; forming a second mask structure on the first gap layer that has an opening exposing at least a portion of the first gap layer disposed along the front edge of the ELG; depositing an electrically conductive material on the first gap layer exposed by the opening of the second mask structure; removing the second mask structure; depositing a second non-magnetic gap layer; and fabricating a shield for the main write pole.
