Title: Innovations of Shohei Mimura in Magnetic Recording Technology
Introduction
Shohei Mimura is a notable inventor based in Kanagawa, Japan, recognized for his contributions to magnetic recording technology. With a total of 5 patents, Mimura has made significant advancements in the field, particularly in the development of magnetic recording media that enhance data protection against forgery.
Latest Patents
Mimura's latest patents include a magnetic recording medium designed to effectively safeguard against data alteration. This invention features a recording material composed of a crystalline alloy containing iron (Fe) and aluminum (Al). The total amount of Fe and Al in the recording material is at least 90 atomic percent, with the atomic ratio of Al to the sum of Fe and Al ranging from 0.30 to 0.45. The material transitions from a disordered phase to an ordered phase upon heating, exhibiting a saturation magnetization of at least 45 emu/g before heating, which decreases by at least 35 emu/g after heating. Additionally, dark regions observable in a bright-field image of the recording material account for 15-60% of the material's area, with a maximum breadth of 10-200 nm. Another patent involves a magnetic recording medium that includes an irreversible recording layer, which undergoes a change in saturation magnetization upon heating. This method allows for the recording of information by converting unheated bars into a heated state, thereby altering the array pattern of heated bars.
