Latest Patents
Mitsumori's latest patents include an innovative optical recording medium. This multilayer optical recording medium is designed such that the recording layer is positioned farther from the surface where a light beam is incident for reading. This design results in a reduced amount of light reaching the surface after being reflected off the recording layer. Another significant patent is for an information recording medium and the process for producing it. This medium boasts excellent jitter characteristics and a considerable difference in reflectance before and after recording. It includes a recording layer made from a material whose reflectance varies with light beam irradiation, and a substrate that supports this recording layer, which primarily consists of a metal nitride. The manufacturing method involves a reactive sputtering technique that utilizes a target made of a metal constituting the metal nitride, with a specific flow ratio of Ar to N set during the process.
