Latest Patents

Ikeda's latest patents focus on creating advanced optical recording mediums. One notable patent describes an optical recording medium that consists of a plastic substrate with a minutely roughened surface and a thin metal film. This design allows for strong absorption of laser light at specific wavelengths, enabling efficient data writing. The unique feature of this medium is its thin metal film, composed of a platinum-group metal and a secondary metal or semi-metal, which limits thermal conductivity to no more than 80% of that of pure platinum group metals. This innovation has resulted in a reduction in jitter, thereby enhancing sensitivity and ensuring high-quality, high-contrast noise ratio (CNR) recordings.

Another patent highlights an optical recording medium structured with a substrate layered with a thin film made from essential components, including a noble metal, chalcogen, and bismuth. This configuration is designed to absorb a laser beam of a specific wavelength, allowing for efficient information recording through the formation of pits and cavities within the film.
