Patent ID: 7085100

Claim:
A magnetic head, comprising: a first pole piece; a second pole piece; a gap layer which separates the first and the second pole pieces; the first pole piece having: a first pole piece layer; a pedestal portion formed on top of the first pole piece layer; the pedestal portion having a first saturation magnetization M S1 ; a top pole portion formed on top of a top surface of the pedestal portion; the top pole portion having a rear edge extending behind a rear edge of the pedestal portion; the top pole portion having a second saturation magnetization M S2 ; the second saturation magnetization M S2 being greater than the first saturation magnetization M S1 ; write coils; an insulator material surrounding the write coils; a top surface of the insulator material being substantially flush with the top surface of the pedestal portion; the top pole portion of the first pole piece being formed over the top surface of the pedestal portion and a first top surface portion of the insulator material; the gap layer being formed over the top surface of the top pole portion; and a top surface of the gap layer being substantially planar over the top pole tip pedestal portion.
