Abstract:
A system according to one embodiment includes a write pole having an end region positioned towards an air bearing surface, a first flare point, and a second flare point positioned between the air bearing surface and the first flare point; and a shield positioned above the write pole, wherein a cross sectional area of the write pole at a point between the first and second flare points along a plane passing through the write pole and oriented about parallel to the air bearing surface is greater than a cross sectional area of the end region of the write pole along a plane oriented parallel to the plane passing through the second flare point. Additional systems and methods are also presented.
