Patent ID: 7113366

Claim:
A device having a leading end, a trailing end and a media-facing surface, said device extending in a y direction from said leading end to said trailing end, in an x direction substantially orthogonal to said media-facing surface and in a z direction perpendicular to both said x direction and said y direction, said device comprising: an electrically conductive coil including a plurality of coil sections disposed adjacent to each other; a ferromagnetic leading pole layer disposed adjacent to said coil sections and extending in said x direction and in said z direction; a ferromagnetic trailing pole layer disposed adjacent to said coil sections and extending in said x direction and in said z direction, said trailing pole layer having a trailing pole yoke width in said z direction; and a trailing pedestal disposed adjacent to said trailing pole layer and to the media-facing surface, said trailing pedestal disposed between said leading pole layer and said trailing pole layer, said trailing pedestal having a trailing pole tip disposed adjacent to said media-facing surface and a trailing pole nose disposed distal to said media-facing surface, said trailing pole tip having a trailing pole tip width in said z direction that corresponds to a track width and having a trailing pole tip length in said x direction, said trailing pole tip having two substantially planar trailing pole tip sides each oriented substantially parallel to an xy plane, said trailing pole nose having a trailing pole nose length in said x direction that is at least twice as large as said trailing pole tip length, further having a trailing pole nose width in said z direction that is at least twice as large as said trailing pole tip width, wherein the trailing pedestal and the trailing pole layer have different material compositions.
