Title: Noriyuki Ogihara: Innovator in Magneto-Optical Technology
Introduction
Noriyuki Ogihara is a prominent inventor known for his contributions to magneto-optical technology. He is based in Ibaraki-ken, Japan, and holds a total of 4 patents. His work has significantly advanced the field of data storage and retrieval.
Latest Patents
Ogihara's latest patents include a magneto-optical recording medium and a magneto-optical disk. The magneto-optical recording medium features a thin film with suitable thermal conductivity, laminated on a magneto-optical film that exhibits excellent durability for repeated recording, reproducing, and erasing. This medium comprises one or multiple layers of thin film containing at least a magneto-optical recording film, supported by a transparent substrate. Additionally, it includes a ferromagnetic reflection film with a reflectance of 70% or higher and a thermal conductivity ranging from 0.05 to 2.0 W/cm·deg.
The magneto-optical disk is designed for recording, reproduction, or erasing with a laser beam. It consists of a four-layer structure, including a first dielectric layer, a magneto-optical recording layer, a second dielectric layer, and a metallic layer. This innovative design allows for improved temperature distribution and enhanced recording/reproduction/erasing characteristics. The disk's structure elevates the temperature over a broader area, resulting in a wider erasing domain and increased signal output by 4 dB compared to traditional three-layer disks.
