Abstract
The presented embodiments generally relate to designing an antenna of an optical transducer (e.g., a near-field transducer or near-field optical source) that focuses the optical energy of a radiation source (e.g., a laser) onto a magnetic media, thereby heating the media. Specifically, the antenna is designed to wrap-around an aperture of the optical transducer such that at least a portion of the antenna is between a main pole of a write head and a surface of the aperture that faces the main pole. Moreover, the antenna may wrap-around the aperture such that it directly contacts the main pole.
