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.
