A perpendicular writer includes a surface, a main pole proximate the surface, a return pole proximate the surface, and a back yoke connecting the main pole to the return pole distal the surface. The return pole is configured such that a magnetization of a portion of the return pole adjacent the surface is held substantially parallel to the surface during a write operation.
