Title: Hiromi Takeda: Innovator in Magnetic Head Technology

Introduction

Hiromi Takeda is a notable inventor based in Hirakata, Japan. She has made significant contributions to the field of magnetic recording technology, holding 2 patents that showcase her innovative spirit and technical expertise.

Latest Patents

Her latest patents include a magnetic head designed to enhance contact with magnetic recording media. This magnetic head features two magnetic cores that are butted against each other, creating a gap between them. A glass is bonded to the upper portion, and a winding is provided on the magnetic cores to facilitate electromagnetic transformation. The design incorporates two grooves on the sliding face of the magnetic head, positioned symmetrically to improve contact with magnetic tapes or other media. Additionally, a protective film is formed on the surface of the sliding face, and the grooves generate a negative pressure that enhances the contact between the magnetic head and the tape.

Another patent involves a metal-in-gap magnetic head, where a pair of magnetic core halves made of ferrite are arranged to oppose each other. Metallic magnetic films are applied to the opposing surfaces, and a hard glass layer along with a chromium layer is used as a gap layer. This innovative design prevents spacing loss when a tape slides over the magnetic head, ensuring optimal performance.
