Title: Sohei Nonaka - Innovator in Magnetic Recording Technology
Introduction
Sohei Nonaka is an inventor based in Sanda-shi, Japan. He is known for his contributions to the field of magnetic recording technology. Although he currently holds no granted patents, his innovative ideas are reflected in his latest patent applications.
Latest Patent Applications
One of his notable applications is for a sputtering target for forming a magnetic recording medium film. This invention aims to create a film with a low ordering temperature while minimizing particle generation. The sputtering target consists of a sintered body with a specific composition represented by the formula: {(FePt)Ag}C, where x, y, and z are defined by atomic percent ranges. Additionally, he has developed a method for producing this sputtering target, which involves hot pressing a mixed powder of AgPt alloy, FePt alloy, Pt powder, and graphite or carbon black powder in a controlled atmosphere.
Another significant application is for a method of manufacturing a Co-base sintered alloy sputtering target. This target is designed for the formation of magnetic recording films that are less likely to generate particles. The method includes blending a Cr—Co alloy powder with other materials to achieve a specific chemical composition, followed by sintering the mixture under pressure.
Conclusion
Sohei Nonaka's work in the field of magnetic recording technology showcases his innovative spirit and dedication to advancing this area. His latest patent applications reflect his commitment to developing solutions that address challenges in the industry.
