Abstract:
A magnetic head assembly having a head surface comprising:a write head including: ferromagnetic first and second pole pieces that have a yoke portion located between a pole tip portion and a back gap portion; a nonmagnetic write gap layer located between the pole tip portions of the first and second pole pieces; an insulation stack with at least one coil layer embedded therein located between the yoke portions of the first and second pole pieces: the first and second pole pieces being connected at their back gap portions; the pole tip portion of the first pole piece having non-overlapping first and second components wherein the first component forms a portion of the head surface and the second component is recessed from the head surface and is magnetically connected to the first component; and the first and second components having a height into the head assembly which is measured from a centerline that is perpendicular to said head surface; each of the first and second components being located along said centerline so that the centerline bisects each of the first and second components with the second component being an extension of the first component into the head assembly along the centerline; the second component having a width that is less than a width of the first component wherein said widths are parallel to the head surface and parallel to a major plane of the write gap layer; a read head; and the first pole piece being located between the read head and the second pole piece.
