Abstract:
In accordance with one embodiment, an apparatus includes a main pole layer of magnetic material; a second layer of magnetic material; a first gap layer of non-magnetic material disposed between the main pole layer and the second layer of magnetic material; a second gap layer of non-magnetic material disposed between the main pole layer and the second layer of magnetic material; wherein the second gap layer of non-magnetic material is disposed 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.
