ABSTRACT:
A system and method are provided for manufacturing a magnetic head. Initially, a coil structure, a first pole layer, and a gap layer are formed. A second pole layer is then deposited to form a pair of flanking portions flanking a central portion of the second pole layer. Thereafter, the second pole layer is masked with a photoresist layer. During manufacture, the flanking portions of the second pole layer work in conjunction with the photoresist layer to substantially protect the coil structure from damage.
