<p>A magnetic head includes a main pole 502, at least one side shield positioned on sides of the main pole, and a trailing shield 504 having a multi-bump structure positioned near a trailing side of the main pole. The multi-bump structure has six junctures along the trailing shield facing the main pole, a first juncture 608 positioned at a media-facing surface 624, a sixth juncture 618 positioned away from the media-facing surface, and second 610, third 612, fourth 614, and fifth 616 junctures positioned along the side of the trailing shield facing the main pole between the first and sixth juncture. An element height of a first face of the trailing shield positioned between the fourth and fifth juncture is less than an element height of a second face of the trailing shield positioned at an end of the trailing shield positioned opposite the media-facing surface. The shield may form a wrap around shield. The multi-bump structure reduces excitation of the shield at the media-facing surface to reduce far and adjacent track interference.</p> |
