摘要： A magnetic head for use in a perpendicular recording system having a novel shield structure that provides exceptional magnetic shielding from extraneous magnetic fields such as from a write coil, shaping layer or return pole of the write head. The shield structure is constructed to have a bottom or leading surface that is generally coplanar with the bottom or leading surface of the shaping layer, but all or a portion of the shield structure is not as thick as the shaping layer so as to have a top surface that does not extend to the same elevation (in a trailing direction) as that of the shaping layer. Making the shields extend to a lower level than the shaping layer improves magnetic performance by reducing flux leakage from the write pole, and also provides manufacturing advantages, such as during the manufacturing of the write pole. These manufacturing advantages include the advantage of having the shields covered with a protective layer of, for example, alumina during the ion milling of the write pole.

摘要： A method for fabricating a magnetic head using a modified P1 cap process. A first pole is formed. A cap is formed above the first pole. A gap layer is formed above the cap. A second pole is formed above the gap layer. Exposed portions of the gap layer are removed. The cap and first pole are milled for creating a shoulder of the first pole tapered upwardly towards the cap. Another method for fabricating a magnetic head includes forming a first pole, forming a gap layer above the first pole, forming a second pole above the gap layer, forming a layer of photoresist above the second pole, patterning the photoresist such that the photoresist covers areas of the gap layer positioned towards the second pole, removing exposed portions of the gap layer, removing part of exposed portions of the first pole for forming steps in the first pole on opposite sides of the photoresist, removing the photoresist, and milling for creating a shoulder of the first pole tapering upwardly towards the cap.

摘要： The invention is a magnetic transducer with separated read and write heads for perpendicular recording. The write head has a trailing shield that extends from the return pole piece toward the main pole piece to form the write gap at the air-bearing surface. One embodiment of the trailing shield is a two part structure with a pedestal and a much smaller tip that confronts the main pole piece at the gap. In one embodiment a sink of non-magnetic, electrically conductive material is disposed in the separation gap between the read head and the flux bearing pole piece. The sink is preferably made of copper and does not extend to the ABS.

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： Methods of fabricating magnetic write heads and electrical lapping guides (ELG's) using a split gap deposition process is described. A removal process is performed on a magnetic material to define a main write pole and to define a corresponding ELG for the main write pole. A first non-magnetic gap layer is deposited. A mask and liftoff process is performed to deposit an electrically conductive material on the first gap layer disposed along a front edge of the ELG. A second non-magnetic gap layer is then deposited and a shield is fabricated for the write pole.

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.
