概要

論文の詳細を見る
Simulations of heat assisted recording using electron beams as a heat source were carried out. A heat flow model was combined with a micromagnetic model to calculate the recording process. The influence of underlayers on the thermal properties of the system is discussed. The results demonstrate the feasibility of heating a medium sufficiently using a low power electron beam source, allowing the use of materials with a higher uniaxial anisotropy. Additional heating of the recording layer may be achieved by patterning the medium into discrete tracks, providing access to materials with Curie temperatures of around 600K.
