New developments in laser-assisted magnetic recording

Recent progress in laser-assisted magnetic recording, which combines optica l and magnetic recording technologies, is described in this paper, This stu dy confirms that laser-assisted magnetic recording is a good candidate for high areal density magnetic recording. Improved disk performance was demons trated in the area of frequency response, media noise, and thermal decay, T he improvements in media design include the change in temperature dependenc e of the recording layer, an increased perpendicular anisotropy, and a ther mally efficient layer structure. These improved media properties results in a high linear density and good thermal stability.
