Title: Kenichiro Mitani: Innovator in Magneto-Optical Technology
Introduction
Kenichiro Mitani is a prominent inventor based in Gifu, Japan, known for his significant contributions to the field of magneto-optical technology. With a total of eight patents to his name, Mitani has made remarkable advancements that enhance the efficiency and functionality of magneto-optical devices.
Latest Patents
Among his latest patents is a method and apparatus for determining the power level of a laser beam in a magneto-optical recording device. This innovative reproducing apparatus is designed to reproduce signals recorded in a magneto-optical disk, which features a layered structure comprising a recording layer, an intermediate layer, and a reproducing layer. The technology involves illuminating laser light from an optical head to the magneto-optical disk at an intensity that prevents the transfer of magnetic domains from the recording layer to the reproducing layer solely by the laser light. In this state, an alternating magnetic field is applied through a magnetic head, facilitating the transfer and expansion of magnetic domains to the reproducing layer, thereby achieving effective domain transfer with expansion.
Another notable patent is for a magneto-optical recording medium that includes an intermediate layer with controlled saturation magnetization. This medium is part of a magnetic domain enlarging/reproducing system that consists of a recording layer and a reproducing layer. It features a gate layer that selectively extracts each magnetic domain within the recording layer, a magnetic field reinforcement layer that enhances the leakage magnetic field reaching the reproducing layer, and a blocking layer that prevents the exchange coupling force from the magnetic field reinforcement layer to the reproducing layer.
