Title: Innovations of Katsuyoshi Chiba
Introduction
Katsuyoshi Chiba is a prominent inventor based in Hachioji, Japan. He has made significant contributions to the field of magnetic recording technology. With a total of 7 patents to his name, Chiba has developed innovative methods that enhance the performance of magnetic disks.
Latest Patents
One of his latest patents is a process for producing a rigid magnetic disk by longitudinally generating a coating type. This method involves applying a magnetic paint containing magnetic powders in a dispersed state to a non-magnetic substrate. By doing so, a magnetic recording film is formed, and surface waves are applied to the film in an undried state. This application improves the dispersibility and orientation of the magnetic powders, resulting in a longitudinally oriented magnetic disk with distinguished electromagnetic properties, such as a high signal-to-noise (S/N) ratio.
Another notable patent is a method for magnetic orientation of a magnetic recording medium using the Meissner effect of a superconductor. This innovative approach allows the magnetic particles of plate hexagonal barium ferrite in the magnetic coating to orient in the longitudinal direction. Consequently, a magnetic recording medium with a magnetic orientation in that direction can be achieved.
