    Abstract: A method includes forming a write pole layer having a front surface, a leading surface, a trailing surface and side surfaces connecting the leading surface to the trailing surface. The method also includes forming side shield layers proximate to the side surfaces of the write pole layer. A patterned sacrificial layer is deposited over the side shield layers, and a trailing surface bevel is formed on the write pole layer.

    Abstract: An apparatus has a main pole layer of magnetic material, a second layer of magnetic material, a first gap layer of non-magnetic material between the main pole layer and the second layer of magnetic material, and a second gap layer of non-magnetic material disposed between the main pole layer and the second layer of magnetic material. The second gap layer of non-magnetic material can be directly adjacent to the second layer of magnetic material. In accordance with one embodiment, this allows the gap to serve as a non-magnetic seed for the second layer of magnetic material. A method of manufacturing such a device is also described.
