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: A data writer can be fabricated by constructing a write pole to continuously extend from an air bearing surface prior to depositing a first gap layer to continuously extend from the ABS in contact with a first write pole sidewall. A first side shield protrusion can then be formed on the air bearing surface to be separated from the write pole by the first gap layer. A second gap layer may be deposited to continuously extend from the first side shield protrusion along the first write pole sidewall to define a dielectric region on which a second side shield protrusion is formed with the second side shield protrusion separated from the write pole by the first and second gap layers and the first and second side shield protrusions each cantilevered from a common side shield body.
