摘要: 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.

摘要: A magnetic device includes a write element having a write element tip that defines a medium confronting surface. The write element is operable to generate a first field at the medium confronting surface. A conductor is proximate the write element tip and first and second conductive leads are connected to the conductor and configured to deliver a current to the conductor to generate a second field that augments the first field. First and second side elements are disposed on opposite sides of the write element tip in a cross-track direction at the medium confronting surface. At least a portion of the first conductive lead is disposed adjacent the first side element on a side opposite the medium confronting surface, and at least a portion of the second conductive lead is disposed adjacent the second side element on a side opposite the medium confronting surface.
