Title: Mikiya Kuroda: Optical Recording and Disc Innovations.

Introduction

Mikiya Kuroda is an inventor associated with Yokohama, Japan, and Victor Company of Japan, Limited. His work includes optical recording technologies designed to support reliable data storage and playback. He is credited with 4 patents.

Latest Patents

Kuroda’s listed patents address optical discs and recording media.

- **Optical disk.** This invention describes a disc that records data as optically readable pits and uses a reproducing laser to read them. Its design combines a light-transmissive substrate and reflective layer with a light-absorbing layer. The absorbing material is selected to absorb strongly in a wavelength band shifted toward longer wavelengths while absorbing less of the reproducing laser’s wavelength. In one variation, the coloring substance is incorporated into the substrate, making a separate absorbing layer unnecessary.

- **Optical recording medium.** This patent describes a medium intended to enable high-density recording without degrading reproduced signals. It uses a transparent resin substrate, a thermochromic layer whose light transmittance changes with temperature, and a reflecting layer. A transparent inorganic heat-radiating layer contacts the thermochromic layer, helping absorb heat generated by the laser spot.

Career Highlights

Kuroda’s patent work reflects an emphasis on optical media and the interaction of light, heat, and material layers. The described technologies seek to improve recording density and preserve the quality of playback signals.
