Introduction: Shunsuke Matsuda, an accomplished inventor based in Osaka, Japan, has made significant contributions to the field of information technology, holding a total of 10 patents to his name. Known for his innovative approaches to recording and reading information, Matsuda has played a pivotal role in advancing the efficiency and effectiveness of data storage methodologies.

Latest Patents: One of Matsuda's notable recent inventions is a method of erasable recording and reading of information. This sophisticated technique involves writing high-density information by ionizing a different element from that of the substrate element and utilizes a focused ion beam for depositing or implanting these ions into the surface layer of the substrate. The erasure process is achieved through sputtering, which scatters the previously written elements using a focused ion beam from another material. For reading, a focused electron beam scans the substrate to detect variations in the energy spectrum created by scattering electrons.

Another significant patent is an innovative optical disc and its manufacturing method. This optical disc design features a resin disc substrate with a recording medium layer and a highly transparent layer. The advanced transparency of this layer exceeds that of the protective resin layer, allowing a laser beam to focus on the recording medium without interference from external contaminants, thereby ensuring high-quality data retrieval.
