Patent ID: 8730617

Claim:
A magnetic head, comprising: a main pole having a trapezoidal cross-section at a media-facing surface thereof, wherein the main pole has a flared shape with a greater width in a cross-track direction at positions away from the media-facing surface than at the media-facing surface; a leading shield positioned near a leading side of the main pole, wherein a leading gap is provided between the main pole and the leading shield; side shields positioned on both sides of the main pole in the cross-track direction adjacent the media-facing surface of the main pole, wherein side gaps are provided between the main pole and both of the side shields; and a trailing gap provided on a trailing side of the main pole at the media-facing surface thereof, wherein a throat height of the side shields at a position closer to the trailing gap is less than the throat height of the side shields at a position closer to the leading gap.
