Title: Kazushi Ogawa: Innovator in Magnetic Recording Technology

Introduction

Kazushi Ogawa is a prominent inventor based in Kanagawa, Japan. He has made significant contributions to the field of magnetic recording technology, holding a total of 3 patents. His work has been instrumental in advancing the efficiency and effectiveness of magnetic recording devices.

Latest Patents

Ogawa's latest patents include a magnetic head with a rectangular-shaped planar spiral coil and a leading core width smaller than the trailing core width. This innovative design features a thin film magnetic recording head that comprises a substrate and two magnetic cores. The second magnetic core is strategically designed to be smaller at the front end compared to the first magnetic core, which helps reduce side erase due to recording magnetic flux fringing. This configuration allows for high-density magnetic recording while maintaining conventional fabrication steps.

Another notable patent is for a magnetic head device that is scanned to a magnetic recording medium. This device includes multiple recording head elements laminated on a base via insulating layers. The design ensures that the size in the track width direction of the first magnetic core layer is smaller than that of the second magnetic core layer, enhancing the overall performance of the magnetic recording process.
