Title: Innovations of Noboru Tsuya in Magnetic Recording Technology

Introduction

Noboru Tsuya is a prominent inventor based in Sendai, Japan, known for his significant contributions to the field of magnetic recording technology. With a total of 15 patents to his name, Tsuya has developed innovative solutions that enhance the performance and reliability of magnetic recording media.

Latest Patents

Tsuya's latest patents include a substrate for magnetic recording medium and a process for producing the same. The first invention provides a substrate designed to improve CSS properties and magnetic properties by forming both macro-concavo-convex and micro-concavo-convex patterns on its surface. This design prevents degradation of CSS properties due to increased friction and wear of the protective layer in contact with the magnetic head. The second invention outlines a process for producing this substrate, ensuring uniform distribution of the macro and micro patterns simultaneously. Additionally, Tsuya has developed a process for preparing magnetic disks, which involves mirror surface-finishing of a substrate with an anodized aluminum film, followed by a chemical dissolution treatment to widen the pores, and finally coating the substrate with a magnetic continuous thin film.
