Title: Kyoya Matsuda: Innovator in Optical and Magnetic Technologies

Introduction

Kyoya Matsuda is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the fields of optical and magnetic technologies, holding a total of 3 patents. His work has been instrumental in advancing the capabilities of optical heads and magnetic disk recording devices.

Latest Patents

Matsuda's latest patents include a substrate unit for an optical head and a method for manufacturing a magnetic disk recording/reproducing head. The substrate unit comprises a light emitting element attachment surface designed to attach a light emitting element that emits laser light substantially in parallel to the attachment surface. It also features a light reflecting surface that changes the direction of the laser light emitted from the light emitting element by a predetermined angle through reflection. Additionally, it includes a light detecting element attachment surface, which is formed on the same two-dimensional plane as the light emitting element attachment surface, for attaching a light detecting element that receives light from the outside.

The magnetic disk recording/reproducing head device includes a slider member made of a magnetic material, a magnetic circuit, and a seal member. The slider member has a sliding surface opposing a recording/reproducing disk, with both end portions in a direction parallel to the sliding surface. It features a groove portion formed in one of the end portions to be parallel to the sliding surface. The magnetic circuit consists of a core member made of a magnetic material, a predetermined magnetic gap between the core member and the slider member, and a coil wound around the core member. The seal member, made of a material with adhesive properties upon melting and a shrinking property upon stiffening, is sealed in the groove portion of the slider member to form an inwardly recessed tapered portion on part of the sliding surface.
