ABSTRACT:
A magnetic recording head having an air bearing surface for confronting a surface of a rotating disc and comprising a pole tip and a generally rounded and substantially planar body attached to the pole tip is disclosed. The width of the pole tip defines a track width of data written to the rotating disc. The generally rounded shape of the top pole body is such that top pole magnetization gradually changes its direction and follows the edges of the body. Further, the pole tip has low remanence, gradual spin structure and no domain walls formed near the pole tip.
