Abstract:
A magnetic head for recording information on a relatively-moving medium, the head having a leading end, a trailing end, and a medium-facing surface, the head comprising:a first soft magnetic layer extending a first distance substantially perpendicular to the medium-facing surface and terminating at a first pole tip disposed adjacent to said medium-facing surface, said first pole tip having a leading edge and a trailing edge, wherein said trailing edge is substantially larger than said leading edge; a second soft magnetic layer extending substantially perpendicular to the medium-facing surface and terminating at a second pole tip disposed adjacent to said medium-facing surface, said second pole tip having a medium-facing area that is substantially larger than that of said first pole tip; and a third soft magnetic layer extending a second distance substantially perpendicular to the medium-facing surface, adjoining said first soft magnetic layer and terminating further than said first pole tip from said medium-facing surface, wherein said second distance is more than half said first distance.
