这项研究应用热辅助磁记录来分析孤立柱状结构介质的温度分布和温度时间转变。与连续薄膜介质相比，阐明了如何使用柱状结构介质实现更高的热分辨率。通过等离激元天线的应用，位图案介质的写入温度比传统介质高10倍以上。相邻柱的温度很大程度上取决于等离子体天线的布置和形状。
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.
