Title: Innovations in Magnetic Recording: The Contributions of Kenichi Masuyama
Introduction
Kenichi Masuyama is a prominent inventor based in Kanagawa, Japan, known for his significant contributions to the field of magnetic recording technology. With an impressive portfolio of 24 patents, Masuyama has continuously pushed the boundaries of innovation in this specialized area.
Latest Patents
Among his latest patents, two notable innovations stand out in the realm of magnetic recording systems. The first patent reveals a magnetic recording system that features a thin-film magnetic head and a magnetic recording medium. This system includes a nonmagnetic support that has a magnetic layer primarily consisting of ferromagnetic particles and a binder resin, with the binder primarily being a vinyl chloride resin. Additionally, the ferromagnetic particles are surface-treated with an organic compound.
The second patent outlines another magnetic recording system that also utilizes a thin-film magnetic head. This system contains a nonmagnetic support with a nonmagnetic layer made up of inorganic nonmagnetic particles and a binder resin. Above the nonmagnetic layer, there is a magnetic layer comprised mainly of ferromagnetic metal particles and its own binder resin, which is primarily a vinyl chloride resin. Notably, the magnetic layer is designed to have a thickness ranging from 0.05 to 1.0 micrometers.
Furthermore, Masuyama has developed a magnetic recording medium featuring a nonmagnetic support with a magnetic layer. This innovation specifies that the magnetic layer is situated on one surface of the nonmagnetic support, consists of ferromagnetic particles, and exhibits a surface roughness ranging from 2 to 10 nanometers. The nonmagnetic support is engineered with multiple layers, including at least one layer containing an antistatic agent, and it possesses a surface roughness between 5 to 30 nanometers on the side opposite to the magnetic layer.
