摘要: Methods for fabrication of tapered magnetic poles with a non-magnetic front bump layer. A magnetic pole may have a tapered surface 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 the tapered surface of the magnetic pole and away 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.

摘要: A perpendicular write head having a wrap around shield and a conformal side gap. In fabricating the write head, the leading edge shield may be chemical mechanical polished down to a level that is substantially even with a chemical mechanical polishing stop layer. Because the leading edge shield and the chemical mechanical polishing stop layer are used as RIE stop for trench RIE, a fully conformal side shield may be formed with a LTE/LES.
