APPARATUSES AND METHODS FOR CONTROLLING NEAR-FIELD TRANSDUCER TO WRITE POLE SPACING
Abstract:
An apparatus includes a waveguide and a near-field transducer adjacent the waveguide. The near-field transducer includes an enlarged region and a peg region extending from the enlarged region towards an air bearing surface. A write pole is adjacent the near-field transducer and include a first portion having an edge extending towards the air bearing surface at a non-orthogonal angle with respect to the air bearing surface. A second portion of the write pole extends orthogonally to the air bearing surface and is in contact with the first portion. The apparatus includes an insulator-filled gap at the air bearing surface between the second portion of the write pole and the peg region of the near-field transducer. The gap is bounded away from the air bearing surface by the enlarged region of the near-field transducer.
