Near field transducer for heat assisted magnetic recording

Abstract

An antenna for heat assisted magnetic recording is disclosed. The antenna includes an optically opaque material and an optically transparent material positioned on the optically opaque material, the optically transparent material includes a half bowtie shape which includes a first half-wing substantially shaped in form of a right angle trapezoid, having a height substantially equal to the overall height of the half bowtie, a second half-wing substantially shaped in form of a mirror image of the first half-wing and formed proximate and coupled to the first half-wing by a substantially rectangular aperture having an aperture width and an aperture height. The aperture height is as small as 1 nm.
