    摘要： A magnetic write head for perpendicular magnetic recording having a write pole with a concave trailing edge. The magnetic write pole can have a trapezoidal shape with first and second laterally opposed sides that are further apart at the trailing edge than at the leading edge. The write head may or may not include a magnetic trailing shield, and if a trailing shield is included it is separated from the trailing edge by a non-magnetic write gap layer. The concave trailing edge improves magnetic performance such as by improving the transition curvature. A method for constructing the write head includes forming a magnetic write pole by forming a mask structure over a deposited write pole material, the mask structure having an alumina hard mask and an image transfer layer such as DURAMIDE®. An alumina fill layer is then deposited and a chemical mechanical polish is performed to open up the image transfer layer. A reactive on etch is performed to remove the image transfer layer and a reactive ion mill or reactive ion etch is performed to remove the alumina hard mask and form a concave surface on the write pole.

    摘要： A method for manufacturing a magnetic write head having a tapered write pole as well as a leading edge taper, and independent trailing and side magnetic shields. The method allows the write pole to be constructed by a dry process wherein the write pole material is either deposited by a process such as sputter deposition or electrically plated and the write pole shape is defined by masking and ion milling. The write pole has a stepped feature that can either be used to provide increased magnetic spacing between the trailing shield and the write pole at a location slightly recessed from the ABS or can be magnetic material that increases the effective thickness of the write pole at a location slightly recessed from the ABS. A bump structure can be further built over that stepped feature to enhance field gradient as well as reduce trailing shield saturation.

    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.
