Abstract: Implementations disclosed herein provide an apparatus comprising a write pole, and a two-layer front shield formed on the write pole, the front shield comprising, a first dielectric material formed on the first layer of the front shield, an active shield control (ASC) device formed between the two layers of the front shield on the first dielectric material configured to synchronize the response to a magnetomotive force (MMF) of a write pole and the front shield, and a second dielectric material formed on the ASC device, wherein the second layer of the front shield is formed only on top of the second dielectric material and the first layer of the front shield.

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.
