Patent ID: 7818760

Claim:
A data writing system, comprising: a medium including an array of cells for storing data; and a write transducer that is moveable relative to the medium to provide a movement of a bearing surface of the write transducer over a selected cell in the array, the write transducer comprising: a plasmon resonator that has a shape that directs lower power density radiation in a first plane to a side of a pin, and the plasmon resonator provides plasmon radiation from the pin at a higher power density to an optical spot intersecting with the selected cell, the plasmon radiation heating the selected cell above a write temperature; and a writer producing a write magnetic field that intersects the selected cell, the writer comprises a write coil and a write core, the write core having poles that define a write gap between the poles, a lower portion of the pin is positioned in the write gap, and the poles being aligned in a second plane that is transverse to the first plane such that the poles do not block the lower power density radiation from reaching the pin.
