Abstract:
1. A magnetic recording transducer having air-bearing surface (ABS) comprising: a pole having a pole tip proximate to the ABS; a side shield having at least one nonconformal portion and a conformal portion between the ABS and the at least one nonconformal portion, the conformal portion extending to the throat height from the ABS in the stripe height direction and being conformal with the pole, the conformal portion adjoining and sharing an edge with a first nonconformal portion of the at least one nonconformal portion, the at least one nonconformal portion extending from a throat height in a stripe height direction perpendicular to the ABS and being nonconformal with the pole, the first nonconformal portion of the at least one nonconformal portion having a takeoff angle configured such that a spacing between the first nonconformal portion of the at least one nonconformal portion and the pole increases with increases in a distance from the ABS, the takeoff angle being at least fifteen degrees and not more than thirty degrees as measured from the ABS; a nonmagnetic gap between the side shield and the pole, the nonmagnetic gap having a first portion and at least a second portion, the first portion of the nonmagnetic gap being between the conformal portion and the pole, the at least the second portion of the nonmagnetic gap being between the at least one nonconformal portion and the pole, the first portion of the nonmagnetic gap having a substantially constant thickness; and at least one coil for energizing the pole.
