| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | 3D heat-assisted magnetic recording on bit patterned media with two recording structures was simulated. In this work, the effect of the dot diameter and the dot thickness on the recording performance and the areal density capability was investigated. Dots with a larger volume have increased thermal stability and allow the minimum track pitch to be reduced. As the dot volume increased, the switching probability, especially that of the bottom structure where a lower write field was applied, was improved and the areal density capability was predicted to exceed 8.5 Tbits/in^2. | |
