Patent ID: 8094419

Claim:
A PMR write head, comprising: (a) a main write pole having a narrow write pole section with a pole tip at an ABS plane, a pole tip thickness in a down-track direction, two sides formed perpendicular to the ABS, a top surface with a top edge having a track width at the pole tip, and a bottom surface with a bottom edge having a width greater than the track width at the pole tip, and a second section formed a certain distance from the ABS wherein the second section has two sides that flare out at a angle θ from the two sides of the narrow section at an end opposite the ABS, said end is a neck height distance from the ABS; and (b) a shield structure comprised of: (1) a trailing shield having a bottom surface formed a certain distance above said top surface of the narrow write pole section and separated therefrom by a gap layer, and two sides at the ABS that are parallel to the down track direction and formed along first and second planes, respectively; and (2) a side shield having a section formed on each side of the narrow write pole section wherein each side shield section has a top surface having a width at the ABS in a cross-track direction, a bottom surface parallel to the top surface and separated therefrom by a pole tip thickness, a side facing away from the narrow write pole section having a length greater than said neck height and formed parallel to the down-track direction and along a first or second plane, a side having a length less than the neck height that is parallel to the nearest side of the narrow write pole section and spaced a side gap distance from said nearest side, and a side that is essentially parallel to the nearest flared side of the second section.
