Title: KianKeong Ooi: Innovations in Closed-Loop Fly Height Control

Introduction

KianKeong Ooi, located in Singapore, has significantly contributed to the field of technology with an impressive portfolio of 45 patents. His innovative work primarily focuses on closed-loop fly height control in heat-assisted recording mediums, showcasing his expertise and dedication to advancing technology.

Latest Patents

Among KianKeong's recent patents, two noteworthy innovations stand out. The first patent describes a closed-loop fly height control system that utilizes a transfer function between harmonic response and heater input. In this system, gain values measured by a variable gain amplifier (VGA) are employed to read servo marks on heat-assisted recording mediums. The innovation determines sector-specific, repeatable gain values that indicate the expected VGA gain at a desired clearance, which are then utilized as input to a closed-loop clearance controller during data writing.

The second patent expands on this concept, using sector-specific, repeatable VGA values for closed-loop fly height control. Again, gain values from the VGA are measured, leading to the same determination of sector-specific values that inform the closed-loop clearance controller, thus optimizing the data writing process on recording mediums.
