Apparatuses and methods for controlling near-field transducer to write pole spacing

摘要

An apparatus is provided that includes a waveguide adjacent an air bearing surface, a near-field transducer comprising a peg having a side orthogonal to the air bearing surface and a write pole adjacent to the waveguide. The write pole includes a first portion extending towards the air bearing surface at a non-orthogonal angle with respect to the air bearing surface, and a second portion in contact with the first portion comprising a side that extends towards and orthogonally contacts the air bearing surface. The second portion or the write pole defines a gap between the side of the peg orthogonal to the air bearing surface and the side of the second portion of the write pole that extends towards and orthogonally contacts the air bearing surface. A method of making a magnetic recording head that includes the provided apparatus is also disclosed.

1. An apparatus comprising:
a waveguide adjacent an air bearing surface; a near-field transducer adjacent the waveguide and comprising a disc and a peg having a side orthogonal to the air bearing surface; and a write pole adjacent to the waveguide comprising a first portion having an edge extending towards the air bearing surface at a non-orthogonal angle with respect to the air bearing surface, and a second portion in contact with the first portion comprising a side that extends towards and orthogonally contacts the air bearing surface,wherein the second portion defines a gap between the side of the peg orthogonal to the air bearing surface and the side of the second portion of the write pole that extends towards and orthogonally contacts the air bearing surface, wherein the gap is further defined on opposing sides parallel to the air-bearing surface by the disc of the near-field transducer and the air bearing surface.
