EM simulation for designing next generation magnetic recording systems

EM simulation impacts many different areas. One of practical and industrial applications is designing magnetic recording systems; higher density and faster recording methods are needed to develop for huge amount of information storage, big data analysis, and so on. In this presentation, we will introduce recent progress of our computational EM studies, especially for technologies using bit patterned media and plasmonic antennas, toward developing next generation magnetic recording systems for higher density and faster recording (Nakagawa et al., J. Appl. Phys., 109, 2011, 07B735-1–07B735-3; Ohnuki et al., Radio Science, 49, in press).
