Patent ID: 8670212

Claim:
A PMR head comprising: a main pole having a trailing edge surface and a leading edge surface and having a 1 st taper on either or both said trailing edge surface and said leading edge surface, wherein said 1 st taper is defined on either or both said trailing edge surface and said leading edge surface by a region of increasing main pole thickness in a positive y-direction away from an ABS edge of said main pole, whereupon said 1 st taper terminates and said main pole has a region of constant main pole thickness, whereat said trailing edge and leading edge surfaces are parallel, extending in said positive y-direction thereafter; at least one tapered yoke having a 2 nd taper, wherein said at least one tapered yoke is formed conformally on a trailing or leading edge surface of said region of constant main pole thickness of said main pole, wherein said 2 nd taper is defined by a region of increasing yoke thickness of said yoke in said positive y-direction, said region of increasing yoke thickness beginning at a yoke edge closest to said ABS edge of said main pole and increasing in a direction away from said ABS edge until said region of increasing yoke thickness becomes a region of constant yoke thickness thereafter; and wherein said yoke edge closest to said ABS edge of said main pole is characterized by a yoke edge face that is parallel to said ABS edge of said main pole and wherein said yoke edge contacts said region of constant main pole thickness of said main pole and is recessed a distance from said ABS edge.
