Latest Patents
Among his latest patents, Tsuda has developed a method of fabricating an alumina nanohole array. This innovative technique involves forming an aluminum thin-film on a substrate at a temperature of -80°C or below, which suppresses crystal grain growth and enhances surface smoothness. The process includes anodizing the aluminum thin-film and texturing it by pressing a mold with an orderly array of projections against it. This method allows for a larger array area to be formed, which is crucial for applications in magnetic recording media. Additionally, Tsuda has patented a method of manufacturing a magnetic recording medium that includes forming an intermediate layer over a non-magnetic substrate and creating a plurality of nano holes in an alumina-containing layer. This method is designed to produce magnetic recording elements suitable for perpendicular recording systems.
