Title: Ryohei Ota: Innovator in Disk Drive Technology

Introduction

Ryohei Ota is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of disk drive technology, particularly through his innovative patent that addresses issues related to rigidity and crosstalk noise in head assemblies.

Latest Patents

Ryohei Ota holds a patent for a "Disk drive and head assembly having hole sequences." This invention discloses hole sequences formed in the metal layer of a trace to adjust rigidity. The design effectively suppresses crosstalk noise resulting from these hole sequences. The suspension includes a trace that transmits signals from a head slider, partially extending along the side surface of the suspension. The trace consists of a metal layer, multiple transmission lines above the metal layer, and an insulating layer. A hole sequence overlapping the transmission lines is formed in part of the metal layer, contributing to a reduction in transmission loss. Additionally, another hole sequence is positioned opposite the hinge portion of the suspension, reducing the rigidity of the wiring structure in that area and preventing interference with the suspension's behavior.
