Title: Tuan H Hua: Innovator in Calibration Technology

Introduction

Tuan H Hua is a notable inventor based in Milpitas, California. He has made significant contributions to the field of calibration technology, particularly in the design of calibration disks used in glide head testing.

Latest Patents

Tuan H Hua holds a patent for a "Calibration disk having discrete bands of calibration bumps." This innovative calibration disk is designed to calibrate the fly height of a head. It features spaced circumferential bands extending from the outer diameter to near the inner diameter of the disk. Each band contains radial and circumferentially spaced asperity emulating bumps, which produce a constant and continuous output signal from a glide head when it flies lower than the maximum height of the bumps. The uniform height of the bumps within individual bands, along with differing average heights across bands, helps avoid errors caused by disk waviness, runout, and contamination. This design allows for glide head calibration without the need for independent fly height measurements, thus eliminating errors and delays in testing.
