Title: Mitsuaki Yoshida: Innovator in Recording Disk Drive Technology

Introduction

Mitsuaki Yoshida is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of recording disk drive technology, holding a total of 11 patents. His innovative work focuses on enhancing the performance and reliability of recording devices.

Latest Patents

One of Yoshida's latest patents is a recording disk drive capable of suppressing vibration of a flexible printed circuit board. This invention features a fixing member that is spaced from a head actuator by a predetermined distance. A flexible printed circuit board extends from the head actuator to the fixing member, superposed on the surface of the fixing member. The design includes a viscoelastic layer and a protecting layer overlaid on the flexible printed circuit board. A clip secures all components together, ensuring stability. When the head slider is positioned, the head actuator adjusts its attitude relative to the recording disk. The inertial force from rotation causes the flexible printed circuit board to vibrate when the actuator block stops rotating. The viscoelastic layer effectively absorbs this residual vibration, thereby suppressing the vibration of the flexible printed circuit board.
