Zusammenfassung:A system according to one embodiment comprises a head having a perpendicular writer, the writer comprising: a first pole structure having a pole tip positioned towards an air bearing surface of the head, the first pole structure having a portion that is recessed from an extent of the pole tip closest the air bearing surface; a return pole having an end positioned towards the air bearing surface of the head; and a gap between the first pole structure and the return pole, wherein the recessed portion is recessed less than about 1.25 microns relative to the extent of the pole tip closest the air bearing surface. Additional embodiments as well as methods are presented.
