Latest Patents
One of his latest inventions is an optical data recording medium that boasts high reliability and large capacity. This invention prevents moisture absorption and swelling of a resin layer formed on one side of a transparent substrate. The optical data recording medium comprises a transparent substrate, a transferred layer of a preformat pattern, and a thin film layer. The surface of the transferred layer in contact with the transparent substrate is made of a resin layer composed of an ultraviolet ray curable resin. This results in an optical data recording medium that has reduced moisture absorption and maintains a swelling ratio of 0.1% or less.
Another significant patent is for an information recording medium composed of a substrate, underlayer, and recording film. This medium is capable of recording information through depressions or pits formed on the recording film when irradiated with a recording energy beam. The recording film features a supporting layer on at least one side, which has a melting point lower than that of the recording film. This design allows for recording pits with a smaller rim inner diameter, achieving a high recording power margin for high-density recording.
