Title: Manabu Koike: Innovator in Magnetic Recording Technology

Introduction

Manabu Koike is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of magnetic recording technology. With a total of 2 patents, his work focuses on enhancing the performance and reliability of magnetic recording media.

Latest Patents

Koike's latest patents include innovative methods for fabricating magnetic recording mediums. One of his patents describes a process where the surface of a non-magnetic base plate is coarsened to achieve the required surface roughness. Ultrasonic vibrations are then applied while the base plate is immersed in a liquid. This method allows for the successive formation of a magnetic recording layer and a protective layer on the base plate. The frequency of the ultrasonic vibrations is ideally maintained between 200 kHz and 1600 kHz. This technique ensures that the surface fractional properties of the magnetic recording medium can be effectively controlled without affecting the floatation height of the magnetic head during operation.
