ABSTRACT:
A magnetic head including an encasing layer having a groove; a nonmagnetic metal layer that has a sidewall located directly above the edge of the groove and that is disposed on a region of the encasing layer away from the medium facing surface; two side shield layers that have sidewalls located directly above the edge of the groove and that are disposed adjacent to the nonmagnetic metal layer on regions of the encasing layer closer to the medium facing surface than the nonmagnetic metal layer; and a pole layer. The pole layer is placed in an encasing section formed of the groove of the encasing layer, the sidewall of the nonmagnetic metal layer, and the sidewalls of the two side shield layers.
