Title: Jeng-Yu Wang: Innovator in Disk Drive Technology

Introduction

Jeng-Yu Wang is a notable inventor based in Fremont, California. He has made significant contributions to the field of disk drive technology, particularly in the area of servo writing. His innovative approach has led to advancements that enhance the performance and reliability of disk drives.

Latest Patents

Wang holds a patent for a groundbreaking invention titled "Disk drive compensating for track squeeze by writing non-circular servo tracks." This patent describes a servo writer that is capable of writing servo sectors on a disk to create non-circular servo tracks. The servo writer includes control circuitry that measures the position of a head over the disk, generating a position signal and a position error signal (PES). The PES is processed with a servo compensator to produce a control signal, which positions the head over the disk. Notably, a disturbance is induced into the servo control system, allowing for the writing of servo sectors that define a servo track, resulting in a non-circular configuration relative to the disk's rotation axis.
