Title: Seiko Uemura: Innovator in Magnetic Head Technology
Introduction
Seiko Uemura is a notable inventor based in Yamaga, Japan. She has made significant contributions to the field of magnetic head technology, holding 2 patents that showcase her innovative approach to engineering.
Latest Patents
Her latest patents include a magnetic head that features a recessed magnetic metal film. This invention involves a slider made of ferrite, with a core formed from a magnetic metal film on its gap confronting surface. The components are bonded together using glass, which sandwiches a non-magnetic film to create a magnetic gap. The magnetic metal film is constructed from materials such as Fe-Ni and Fe-Al-Si, utilizing thin-film fabrication technology like sputtering. A recessed portion is designed on the magnetic metal film, ensuring it is retracted from the medium confronting surface by a specific depth. This design prevents color change in the magnetic metal material, thereby maintaining the performance characteristics of the magnetic head.
Another patent focuses on a magnetic head apparatus that incorporates multiple recessed magnetic metal films. Similar to her previous invention, this design also features a ferrite slider and a core with a magnetic metal film. The bonding glass and non-magnetic film are utilized to create the magnetic gap. The recessed portion is again retracted from the medium confronting surface, ensuring that the magnetic metal material remains stable and effective.
