Latest Patents

Higashimaru's latest patents include a method and apparatus for manufacturing a multi-layer optical information recording medium. This invention features a transfer layer on a mold surface with a thickness distribution that is thick in the inner round portion and gradually thinner toward the outer round portion. An adhesive layer is formed between the signal substrate, which bears a signal recording film, and the mold. The adhesive layer also has a thickness distribution that is thin in the inner round portion and thicker toward the outer round portion. This opposing thickness distribution results in a uniform isolation layer.

Another notable patent is a method of manufacturing an optical information recording medium that allows for optical recording and reproduction of signals. This medium consists of a signal substrate, a signal recording layer, and a transparent cover layer with two distinct transparent layers. The first layer has a predetermined thickness distribution, while the second layer is designed to ensure uniform total thickness. This innovative design enhances the efficiency of signal recording and reproduction.
