Introduction: Hitoshi Inoue, an accomplished inventor based in Kokubunji, Japan, has made significant contributions to the field of magnetic disk technology. With a total of two patents to his name, he has proven himself as an innovative force within his company, Hitachi, Ltd. His work focuses on improving the performance and efficiency of magnetic recording media.

Latest Patents: Hitoshi Inoue's latest patents highlight his ingenuity and technical expertise. One of his significant patents is titled "Process for producing a rigid magnetic disk by longitudinally generating." This innovative process involves applying a magnetic paint that contains magnetic powders in a dispersed state onto a non-magnetic substrate. By applying surface waves to the magnetic recording film during the undried state, the dispersibility and orientation of the magnetic powders are enhanced. This results in a longitudinally oriented, coating-type magnetic disk exhibiting excellent electromagnetic properties, such as a high signal-to-noise (S/N) ratio.

Another noteworthy patent by Inoue is related to the "Hard disk magnetic recording medium comprising magnetic powder." This patent describes a method for manufacturing magnetic paint by mixing a resin composition powder, which acts as a dispersing binder for the magnetic powder, with the magnetic powder. This mixture is then ground under high shear stress. The magnetic recording medium produced from this paint can achieve a magnetic coating film with a uniform film thickness of not more than 0.9 micrometers and a surface roughness of less than 0.05 micrometers Ra before surface finishing.
