Mari Fujii is a notable inventor based in Chiba, Japan. She has made significant strides in the field of magnetic recording technology. Her work focuses on creating a magnetic recording medium that is resistant to forgery and data alteration.
Latest Patents
Mari Fujii holds a patent for a magnetic recording medium. This invention is designed to effectively protect against forgery by altering recorded data. The magnetic recording medium comprises 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 (Fe + Al) ranging from 0.30 to 0.45. The recording material transitions from a disordered phase to an ordered phase upon heating. It exhibits a saturation magnetization of at least 45 emu/g before heating and decreases by at least 35 emu/g after heating. Notably, dark regions can be observed in a bright-field image of the recording material through transmission electron microscopy, accounting for 15-60% of the material in areal ratio, with a maximum breadth of 10-200 nm.
