Title: Cheol-won Lee: Innovator in Optical Disk Technology

Introduction

Cheol-won Lee is a prominent inventor based in Euiwang, South Korea. He has made significant contributions to the field of optical disk technology, holding a total of 3 patents. His work focuses on enhancing the performance and efficiency of optical disk apparatuses.

Latest Patents

One of his latest patents is the "Track compensation apparatus of magnetooptical disk apparatus." This invention addresses the issue of track crossing signals not being generated due to an offset detection flag (ODF) region or defects in a disk. The apparatus includes a missed track compensating processor that compensates for missed track signals when the light beam passes through the ODF region. Additionally, it features a track counter that mixes a pulse signal from a monostable multivibrator with a compensation signal, allowing for accurate counting of tracks crossed by the light beam.

Another notable patent is the "Optical disk high-speed search control device." This device and method perform a coarse seek to control the crossing speed of optical tracks. By counting the track traverse signal of an optical head, the device enables the optical head to reach a target track quickly and accurately in a single driving operation. This innovation reduces access time and simplifies the driving circuit of the access device, minimizing the time required for fine seeking.
