Title: The Innovations of Shuji Sudo
Introduction
Shuji Sudo is a prominent inventor based in Mooka, Japan. He has made significant contributions to the field of magnetic head technology, holding a total of 2 patents. His work has been instrumental in advancing the capabilities of magnetic recording devices.
Latest Patents
One of Shuji Sudo's latest patents is for an MR composite-type thin-film magnetic head. This innovative design includes 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. The recording induction coil is located 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 greater.
Another significant patent involves a composite magnetic head that includes a slider plate and a back board. In this design, a slider plate that secures a front magnetic core at a predetermined position is joined to a back board equipped with a back yoke and a coil layer. This configuration allows for the formation of a transducer element, which consists of the front magnetic core, the back yoke, and the coil layer, thereby creating a composite magnetic head.
