Title: Innovations of Hideji Takahashi
Introduction
Hideji Takahashi is a notable inventor based in Mooka, Japan. He has made significant contributions to the field of magnetic technology, particularly in the development of thin-film magnetic heads. With a total of 3 patents to his name, his work has had a considerable impact on the industry.
Latest Patents
Takahashi's latest patents include an MR composite-type thin-film magnetic head. This innovative design features an MR element that serves as a reproducing element and a recording induction coil. The MR element is strategically placed between a lower magnetic pole and an intermediate magnetic pole, while the recording induction coil is positioned between the intermediate magnetic pole and an upper magnetic pole. Notably, a portion of the upper magnetic pole near the recording gap is made from a material with a high saturation magnetic flux density of 1.4 T or higher. Additionally, the intermediate magnetic pole is constructed from a material with a high resistivity of 80 μΩ·cm or higher.
Another significant patent is for a composite magnetic head. This invention consists of a pair of magnetic core pieces made from an oxide-type magnetic material, bonded together to form a main magnetic circuit with a magnetic gap in between. A thin magnetic metal layer is formed on the magnetic gap-opposing surface of at least one of the core pieces, creating an auxiliary magnetic circuit. The columnar crystal structure of this layer is designed to enhance performance, with the orientations of the crystals being perpendicular to the magnetic gap-opposing surface.
