    摘要: 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.

    摘要: A magnetic write head having write pole and a wrap-around-trailing magnetic shield having side portions that are separated from the write pole by tapered non-magnetic side gap layers. The tapered non-magnetic side gap layers provide a non-magnetic side gap width that increases with increasing distance from the ABS, thereby providing optimal protection against adjacent track interference at the ABS while minimizing write field loss to the shield in regions away from the ABS.

    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 method for forming a magnetic write head having a trailing shield with a tapered and stepped, self aligned trailing magnetic shield. The shield has a tapered portion that tapers away from the write pole as it extends away from the ABS. This tapered portion helps to channel flux to the pole tip portion of the shield, while preventing the loss of write field to the shield. The stepped portion of the shield further helps to prevent the loss of write field and also defines a secondary throat height of the shield that can be accurately located relative to the air bearing surface.

    摘要: A method for manufacturing a magnetic write head having a write pole with a tapered, stepped trailing edge. The method includes depositing a magnetic write pole material over a substrate, and then forming a magnetic step structure over the magnetic write pole material. A mask structure is then formed, which includes a multilayer hard mask formed over the magnetic write pole material and the magnetic step structure. An ion milling process is then performed to remove a portion of the write pole material to define a write pole. A non-magnetic material can be deposited and ion milling performed to form non-magnetic side gap layer at the sides of the write pole. A multi-step reactive ion milling process can then be performed to remove the remaining hard mask from over the write pole.
