ABSTRACT:
A system according to one embodiment includes a magnetic pole; a bump structure above the pole, the bump structure having a first surface oriented at a first angle between 1° and 89° from a plane of deposition of the pole, and a second surface oriented at a second angle between 1° and 89° from the plane of deposition of the pole, wherein the second angle is greater than the first angle; and a shield above the bump structure. A method according to one embodiment includes forming a bump layer above a magnetic pole; removing a portion of the bump layer for forming a step therein; and milling the bump layer for defining thereon a first surface oriented at a first angle between 1° and 89° from a plane of deposition of the bump layer, and a second surface oriented at a second angle between 1° and 89° from the plane of deposition of the bump layer, wherein the second angle is greater than the first angle.
