Abstract:
A perpendicular recording head is provided having a bottom pole, a writer pole disposed above the bottom pole, and a top shield disposed above the writer pole. The bottom pole and the top shield are both magnetically coupled to the writer pole. The writer pole includes a concave facing surface that faces the top shield. The top shield can include a convex surface that faces the writer pole. The top shield can also include a pedestal that protrudes towards the writer pole.
