Title: The Innovations of Sang-eun Baek

Introduction

Sang-eun Baek is a prominent inventor based in Incheon-si, South Korea. He has made significant contributions to the field of hard disk drive (HDD) technology, holding a total of 10 patents. His work focuses on improving the performance and reliability of HDDs through innovative methods and systems.

Latest Patents

One of Sang-eun Baek's latest patents is titled "Methods calculating RRO and RRO compensation value in HDD." This patent provides a method for calculating repeatable runout (RRO) of a hard disk drive in the frequency domain. It includes a method for calculating a compensation value using the RRO calculation method and recording media used for this purpose. The method involves calculating a first set of frequency coefficients to represent the RRO by analyzing a position error signal (PES) sampled in a target track while the head follows that track. The RRO is then calculated using these frequency coefficients.

Another notable patent is the "Method and apparatus compensating disturbance in state control device." This invention discloses a method and system for compensating disturbances applied to a plant, such as an HDD component, controlled by a state control device. The device includes an estimator and controller that generates control signals in response to the estimated state of the plant, ensuring optimal performance.
