Title: Seizi Yoneoka: Innovator in Magnetic Head Technology
Introduction
Seizi Yoneoka is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of magnetic head technology, holding a total of 3 patents. His work primarily focuses on enhancing the performance and reliability of magnetic head assemblies.
Latest Patents
One of his latest patents is for a magnetic head assembly that features thin-film dummy patterns on the surface of a gimbal spring. This innovative design includes a slider equipped with a magnetic head, which is mounted on the gimbal spring using an adhesive. The gimbal spring is supported by beam portions of a load beam, and a thin-film wiring pattern extends to the surface of the gimbal spring. The terminal portion of this wiring pattern connects to input/output terminals on the slider, ensuring a secure and efficient connection.
Another significant patent involves a magnetic head suspension assembly with an adhesion limiting structure. In this design, at least one slit is formed in the gimbal spring, which opposes the adhesion surface of the slider. This feature minimizes the transfer of temperature-induced expansion and contraction from the gimbal spring to the slider. Additionally, the Young's modulus of the adhesive agent used is carefully selected to ensure that the warping of the slider remains within an acceptable range, thereby stabilizing the floating performance of the slider.
