Introduction
Hidefumi Funaki is a notable inventor based in Hamura, Japan. He has made significant contributions to the field of magnetic recording technology. With a total of 3 patents to his name, Funaki continues to push the boundaries of innovation in his industry.
Latest Patents
One of Funaki's latest patents involves a flexible magnetic recording medium. This medium comprises an underlying film that includes first and second films successively formed on a substrate. The first film consists of an alloy of nickel and iron, along with a magnetization adjusting component. The amount of this component is carefully adjusted to ensure that the first film has a saturation magnetization of less than or equal to 500 e.m.u./cc. The magnetization adjusting component can be molybdenum or a combination of molybdenum and copper, with a weight percentage ranging from 12 to 50%. Alternatively, titanium or silicon may also be used. The alloy may be Permalloy, and the substrate is typically a polyester film.
Another patent focuses on a sputtering apparatus designed for creating thin magnetic films. In this apparatus, a cathode with a target made of ferromagnetic material is positioned in an evacuated vessel. The target is sputtered with ions to form thin films on a substrate. The design includes a magnet on a backing plate, a shield made of similar material to the target, and a metal block surrounding the magnet. Additionally, a passage for cooling water is integrated into the cathode to maintain optimal operating conditions.
