Abstract
Official abstract text for this publication.
An apparatus according to one embodiment includes a near field transducer comprising a conductive metal film having a main body, a notch extending from the main body, and a notch diffusion barrier layer interposed between the notch and the main body. An apparatus according to another embodiment includes a write pole, and a near field transducer adjacent the write pole. The near field transducer includes a conductive metal film having a main body, a notch extending from the main body, and a notch diffusion barrier layer interposed between the notch and the main body. The notch diffusion barrier layer includes a metal selected from a group consisting of Rh, W, Mo, Ru, Ir, Co, Ni, Pt, B, and alloys thereof. Additional systems and methods are also presented.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus, comprising: a write pole; and a near field transducer comprising a conductive metal film having a main body, a notch extending from the main body, and a notch diffusion barrier layer interposed between the notch and the main body, wherein the notch diffusion barrier layer, as formed, includes alloys of gold with at least one of Rh, W, Mo, Ru, Ir, Co, Ni, Pt, B. 2. The apparatus as recited in claim 1 , comprising an ap…
