概要

• 論文の詳細を見る

•   This research applied thermally assisted magnetic recording to analyze both temperature distributions and temperature time transitions of isolated columnar structured media. It was clarified how a higher thermal resolution could be achieved using columnar structured media compared with continuous film media. With the application of a plasmon antenna, bit-patterned media achieved a writing temperature of more than 10 times higher than that of conventional media. Temperatures of adjacent columns strongly depend on the arrangement and the shape of a plasmon antenna.
