| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In a 3D heat assisted magnetic recording method using a double-layer bit patterned medium (BPM), we investigated the relationship between the structure and thermal conductivities of the BPM and the thermal distribution of the recording layer. We used COMSOL Multiphysics software, which combines electromagnetic field analysis and thermal conduction analysis. As a result, thermal distribution could be made steeper by completely separating the bits including underlayer of MgO with SiO2 and making the thermal conductivity of the recording layer anisotropic and the heat sink layer isotropic. In this calculation, boundary thermal conductance was set between different materials. This study suggests that it is possible to prevent adjacent track dots on the upper layer from being rewritten during lower layer recording, and also to prevent the lower layer from being rewritten during upper layer recording. | |
