Abstract
A magnetic writer includes a high magnetic moment write pole layer on a main write pole, the write pole layer including a proximal end recessed from the air bearing surface, and a Wide Area Track Erasure (WATER) reservoir recessed from the proximal end of the write pole layer and transverse to a longitudinal direction of the main write pole. The write pole layer may be conformal in shape to, but have smaller dimensions relative to, the main write pole, such that a distance between their outer surfaces is generally constant in a flare region. The WATER reservoir width, in a cross-track direction, may be greater than or equal to the maximum width of the main write pole.
