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 manufacturing a magnetic write head having a leading magnetic shield and a trailing magnetic shield that are arranged to prevent the lost of magnetic write field to the trailing magnetic shield. The write head includes a non-magnetic step layer that provides additional spacing between the trailing magnetic shield and the write pole at a region removed from the air bearing surface.

A method and system for providing a perpendicular magnetic recording (PMR) transducer from pole layer(s) are disclosed. First and second planarization stop layers are provided on the pole layer(s). A mask is provided on the second planarization stop layer. A first portion of the mask resides on a portion of the pole layer(s) used to form the PMR pole. The PMR pole is defined after the mask is provided. An intermediate layer surrounding at least the PMR pole is provided. A first planarization is performed on at least the intermediate layer. A portion of the second planarization stop layer is removed during the first planarization. A remaining portion of the second planarization stop layer is removed. A second planarization is performed. A portion of the first planarization stop layer remains after the second planarization. A write gap and shield are provided on the PMR pole and write gap, respectively.
摘要:
A magnetic write head having a tapered trailing edge and having a magnetic layer formed over a trailing edge of the write pole at a location recessed from the ABS, the magnetic layer being separated from the trailing edge of the write pole by a thin non-magnetic layer. The thin non-magnetic layer is preferably sufficiently thin that the magnetic layer can function as a portion of the write pole in a region removed from the ABS. A trailing magnetic shield is formed over the write pole and is separated from the write pole by a non-magnetic trailing gap layer. A non-magnetic spacer layer can be formed over the magnetic layer to provide additional separation between the magnetic layer and the trailing magnetic shield.

Methods for fabrication of leading edge shields and tapered magnetic poles with a tapered leading edge are provided. The leading edge shield may be formed by utilizing a CMP stop layer. The CMP stop layer may aid in preventing over polishing of the magnetic material. For the tapered magnetic poles with a tapered leading edge, a magnetic material is deposited on a planarized surface, a patterned resist material is formed, and exposed magnetic material is etched to form at least one tapered surface of the magnetic material.

A method for manufacturing a magnetic write head having a write pole and a trailing wrap around magnetic shield, and having a non-magnetic step layer and a non-magnetic bump to provide additional spacing between the write pole and the trailing wrap around shield at a location removed from the air bearing surface. A magnetic write pole material is deposited on a substrate and a non-magnetic step layer is deposited over the write pole. A reactive ion milling can he used to pattern the non-magnetic step layer to have a front edge that is located a desired distance from an air hearing surface. A patterning and ion milling process is then performed to define a write pole, and then a layer of alumina is deposited and ion milled to from a tapered, non-magnetic bump at the front the non-magnetic step layer.
