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.
