Title: Chun-sup Kim: Optical Disc Signal Processing Inventor.

Introduction

Chun-sup Kim is an inventor based in Suwon, South Korea. His work includes inventions for improving optical-disc tracking and reducing signal distortion during high-speed playback. Kim is associated with Samsung Electronics Co., Ltd. and is credited with 7 patents.

Latest Patents

One of Kim’s latest patents, “Apparatus and Method for Generating a Tracking Error Signal Using First Through Fourth Optical Detector Elements,” describes a system that adaptively generates a tracking error signal. It compares signals from four optical detector elements and selects suitable signal pairs to compensate for phase errors caused by uneven pit depths on an optical disc. This approach is designed to produce a more reliable tracking signal.

Another patent, “Signal Distortion Minimization Apparatus in High Speed Optical Disc Reproducing Device,” addresses distortion during high-speed optical-disc playback. The apparatus uses gain amplification, frequency and boost control, a boost filter, and group-delay processing to account for differences in pickup and disc characteristics.
