Title: Shin-ichi Ogawa: Inventor in Magnetic Recording Technology.
Introduction
Shin-ichi Ogawa is an inventor associated with Ichihara, Japan, and Showa Denko Kabushiki Kaisha. His recorded portfolio includes 3 patents, including inventions concerning magnetic recording media.
Latest Patents
Ogawa’s listed patents describe a magnetic recording medium built on a non-magnetic substrate, such as glass or carbon. The design places a silicon layer on the substrate, followed by a layer of a platinum-group element or alloy, or carbon. Silicon diffusing from the adjacent layer partially silicifies the platinum-group material or makes the carbon at least partially amorphous.
The structure also includes a chromium or chromium-alloy undercoat, a cobalt-alloy magnetic layer, and a protective carbon overcoat. An optional lubricating layer may be added above the overcoat. The described inventions focus on the layered construction and materials of the recording medium.
