Title: Kazuo Ino: Innovator in Magnetic Head Technology

Introduction

Kazuo Ino is a prominent inventor based in Matsubara, Japan, known for his significant contributions to magnetic head technology. With a total of nine patents to his name, Ino has made remarkable advancements in the field of magnetic recording.

Latest Patents

One of his latest patents is for a magnetic head designed to suppress the generation of pseudogap. This innovative magnetic head consists of a pair of magnetic core halves, heat-resistant thin films, and ferromagnetic thin films. The core halves are made of a ferromagnetic oxide, such as ferrite, and are positioned opposite each other through a non-magnetic material like SiO2 to create a magnetic gap. The gap-forming faces are meticulously etched and purified to expose a crystal of the ferromagnetic oxide. Additionally, a heat-resistant thin film of SiO2 is formed on each gap face, with a ferromagnetic thin film of sendust layered on top. The design ensures that the thickness of the heat-resistant thin film is appropriately set to enhance performance. Another notable patent involves a MIG (Metal in Gap) magnetic head, which features single-crystal ferrite core halves and a thin ferromagnetic film. This design minimizes the pseudo-gap problem and improves reproduction output.
