Abstract
A data writing system includes an array of cells for storing data and a write transducer that moves over a selected cell in the array of cells. The write transducer includes a writer producing a write magnetic field that intersects the selected cell. The write transducer also includes a plasmon resonator that is adjacent the writer. The plasmon resonator is shaped to receive lower power density radiation and to provide plasmon radiation at a higher power density to an optical spot intersecting with the selected cell. The plasmon radiation heats the selected cell above a write temperature.
