Paper Abstract

The Micro-RAS was applied to the in situ detection of microscopic and local contaminants on the magnetic disks and heads, which sometimes limited the progress of the new technology for the developing HDD. As a result, we succeeded in detecting and identifying the surface contaminants with the Micro-RAS, which had never been detected with the normal Micro-IR. The enhancement factor of the Micro-RAS to the Micro-IR was estimated to be about 20, especially for the detection of the adsorbed species whose vibrational mode was perpendicular to the surface.
