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 method for forming a magnetic write pole with a trapezoidal cross-section is described. The method consists of first forming a magnetic seedlayer on a base followed by depositing a removable material layer on the seedlayer, and then a resist layer on the removable material layer. A trench is then formed in the resist, and the resist is heated to cause the cross-sectional profile of the trench to assume a trapezoidal shape. The resist is then capped with another resist layer and further heated to cause the width of the trapezoidal trench to become narrower. The cap layer and removable material layer at the bottom of the trench are then removed and the trench filled with magnetic material by electroplating. The resist and seedlayer external to the trench are finally removed to form a write pole with a trapezoidal cross-section.
