Patent ID: 7500255

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 is shaped to receive lower power density radiation and to provide plasmon radiation at a higher power density to an optical spot that is under a lower end of a pin in the plasmon resonator and that is intersecting with the selected cell, the plasmon radiation heating the selected cell above a write temperature; and a writer including an electrical conductor having an electrical conductor portion that carries a write current and that is at the bearing surface and that overlies the lower end of the pin for carrying the write current next to the lower end of the pin, the write current next to the lower end of the pin producing a write magnetic field that intersects the selected cell.
