Latest Patents
One of Yoshio Shirai's key patents is related to an optical disc and its fabrication method. This patent describes a process where, on a replica substrate, a reflection layer, a first dielectric layer made of ZnS—SiO, a recording layer made of a phase change type recording material, and a second dielectric layer made of ZnS—SiO are successively formed. Additionally, a reaction protection layer made of SiN or SiO is formed on the second dielectric layer, resulting in an information signal portion. A light transmissivity sheet is created through an adhesive layer, coating the information signal portion and forming a light transmission layer. When the reaction protection layer is not formed, a reaction protection resin layer made of an ultraviolet ray setting resin is applied to coat the information signal portion. This innovative approach enhances the performance and reliability of optical discs.
