Andreas Moser is a research staff member at the Hitachi San Jose Research Center. He received his Ph.D. degree in physics at the University of Basel, Switzerland, where he imaged and manipulated vortices in high-Tc superconductors using low temperature magnetic force microscopy. Since 1996, he focuses on the characterization of high-density magnetic recording media and the exploration of new recording schemes, capable of extremely high-density recording. He is currently working on the recording physics of high-density perpendicular recording. Andreas Moser has authored and co-authored eight patents and more than sixty technical publications in peer-reviewed journals.
