Title: Norifumi Miyamoto: Innovator in Magnetic Head Technology
Introduction
Norifumi Miyamoto is a distinguished inventor based in Kanagawa, Japan. He has made significant contributions to the field of magnetic disk drive technology, holding two patents that showcase his innovative approach to improving performance and reliability in data storage devices.
Latest Patents
Miyamoto's latest patents include a magnetic head tester and a method of manufacturing magnetic disk drives. The magnetic head tester is designed to be an inexpensive solution that utilizes components from a production hard disk drive (HDD). This invention allows for functions that closely mimic those of a production HDD. The design features a lightweight and simple head gimbal assembly (HGA) fixing mechanism, which can secure the HGA to the actuator arm using various methods, including a light holding spring, air pressure clamping, or elastic deformation of a rubber clamping member. The servo control is achieved through the actuator of a production voice coil motor (VCM), ensuring precise operation.
The second patent focuses on a magnetic disk drive that incorporates a function for managing flying height based on thermal protrusion. This phenomenon occurs when the write head's material expands due to Joule heat, causing the head's flying surface to protrude toward the magnetic disk. Miyamoto's invention allows for accurate measurement and management of flying height, enhancing the reliability of magnetic disk drives during operation.
