Title: Wing Tsang Tang: Innovator in Hard Disk Drive Technology

Introduction

Wing Tsang Tang is a notable inventor based in Palo Alto, CA (US), recognized for his contributions to hard disk drive technology. With a total of 10 patents, Tang has developed innovative methods and apparatuses that enhance the reliability and performance of disk drives.

Latest Patents

One of Tang's latest patents focuses on methods and apparatus to detect surface characteristics on magnetic read/write heads. This invention aims to improve hard disk drive reliability by detecting predetermined surface characteristics, such as head slider protrusions that can lead to damage. By identifying these protrusions, drives with a higher chance of failure can be excluded from testing, thereby enhancing the quality of the remaining disk drives. Another significant patent addresses head shock resistance and head load/unload protection. This invention involves a slider in a disk drive that is shock-protected with an overcoat layer, which absorbs shock and reduces wear. The protective layer is strategically applied to areas of the slider that are prone to contact with the disk, ensuring data integrity and reducing disk errors.
