Title: Innovations of Ping-Kai Huang in Optical Storage Systems

Introduction

Ping-Kai Huang is a notable inventor based in Chung-Ho, Taiwan. He has made significant contributions to the field of optical storage systems, particularly in the area of disc rotation control. With a total of two patents to his name, Huang's work focuses on enhancing the performance and reliability of optical storage devices.

Latest Patents

Huang's latest patents include a "Method and apparatus for disc rotation control in an optical storage system based on detected extent of disc warping." This invention provides an apparatus capable of generating a focusing error signal from light reflected by a loaded optical disc. The apparatus features a focus controller that processes the focusing error signal to obtain a focus output signal. Additionally, it includes a low pass filter unit that processes the focus output signal through low pass filtering to obtain a filtered signal. A direct current level remover is also part of the system, which removes the direct current component of the filtered signal to yield a warp-indicating signal. The speed controller then compares this warp-indicating signal with a predetermined threshold value to determine the extent of warping of the optical disc. This innovative approach allows the optical storage system to limit the maximum rotation speed of the optical disc based on the results of the comparison made by the speed controller.

Another patent by Huang is titled "Method and device for disc rotation control in an optical storage system based on detected extent of disc warping." This digital signal processing device generates a focusing error signal from light reflected by an optical disc loaded in the optical storage system. It includes a low pass filter that removes high-frequency components of the focusing error signal to obtain a filtered signal. Similar to his previous invention, a direct current level remover is utilized to extract a warp-indicating signal. The controller then compares this signal with a predetermined threshold value to assess the extent of warping of the optical disc, allowing for effective control of the optical storage system's maximum rotation speed.
