    摘要： A method for manufacturing a magnetic write head having a that has a write pole with a tapered trailing edge in a pole tip region, and a trailing shield that has a leading edge that tapers away from the write pole at an angle that is greater than that taper angle of the trailing edge of the write pole. The magnetic head has a step feature with a front edge that is recessed from the ABS. In one embodiment a magnetic wedge is formed over the tapered surface of the write pole. In another embodiment, a non-magnetic bump is formed over a first tapered portion of the write pole adjacent to the front edge of the step feature, and a non-magnetic wedge is formed over a second tapered portion of the write pole and extends from the non-magnetic bump to the air bearing surface.

    摘要： 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.

    摘要： A method for manufacturing a magnetic write head having a write pole with a tapered leading edge formed on a substrate having a tapered surface and a wrap-around, trailing magnetic shield. The method uses a multi-layer anti-reflective coating prior to formation of the shield so that reflection from the tapered surface of the substrate does not affect the lithography of the mask used to form the trailing shield. The multi-layer antireflective coating is constructed of materials that can be left in the finished head, thereby eliminating problems associated with removal of the anti-reflective coating.

    摘要： A stepped main pole for a perpendicular write head and methods of making the stepped main pole. The stepped main pole has a main pole tip and a base portion. The main pole tip has a surface that forms part of the ABS and a first thickness. The base portion extends from the main pole tip and has a thickness that varies from the first thickness to a second thickness to form a slanted surface with an apex angle adjacent the main pole tip. By placing the base portion away from the ABS and providing a thickness that increases in a direction away from the ABS, the stepped pole can provide the necessary magnetic flux for writing, while avoiding undesired leakage and fringing. To form embodiments of the stepped main pole of the invention, a fluorine-based reactive ion etch (RIE) may be used. By using an RIE to define the stepped main pole, the apex angle can be better controlled and tight edge control can be achieved.
