Title: Innovations of Kwong-Tat Chan in Hard Disk Drive Technology

Introduction

Kwong-Tat Chan is a notable inventor based in Pleasanton, California. He has made significant contributions to the field of hard disk drive technology, holding two patents that showcase his innovative methods for writing servo information onto disks.

Latest Patents

His latest patents include "Utilization of the acceleration zone in ammonite servo writing" and "Window timing adjustment for spiral bursts." The first patent describes a method for writing servo information onto a hard disk drive using a servo writer. This method involves accelerating a head to a constant velocity across a disk, which is divided into an acceleration zone and a constant velocity zone. The head writes a spiral servo pattern in the constant velocity zone, and a final servo pattern is also written using a servo reference pattern in the acceleration zone. The second patent focuses on writing a plurality of spiral servo signals with a head, adjusting the timing window based on a position error signal to compensate for irregularities in the spiral servo signals.
