Abstract:
Methods for fabrication of tapered magnetic poles with a non-magnetic front bump layer. A magnetic pole may have a plurality of tapered surfaces at or near an air bearing surface (ABS), wherein a thickness of the write pole increases in a direction away from the ABS. A non-magnetic front bump layer may be formed on one or more of the tapered surfaces of the magnetic pole at a distance from the ABS. The front bump layer may increase the separation distance between a shield layer and the magnetic pole near the tapered surface, thereby improving the performance of the write head.
