Title: The Innovations of Kechen Cheng
Introduction
Kechen Cheng is a notable inventor based in Sunnyvale, California. He has made significant contributions to the field of technology, particularly in the development of servo systems for disk drives. His innovative approach has led to the creation of a patent that enhances the performance and reliability of data storage devices.
Latest Patents
Kechen Cheng holds a patent for a "Servo system for a disk drive." This invention involves a servo system that intermittently samples servo sectors from a data disk to determine the position of the read/write head and maintain on-track alignment. A glass scale measures the movement of the transducer head, providing a velocity signal. An integrator processes this velocity signal to produce a fill-in position signal. This signal is then combined with the position signal from the last sampled servo sector, allowing for accurate position compensation when the head is between servo sectors. The system also includes an on-track detector circuit and a damping circuit that minimizes movement of the transducer head when it is in the on-track position. Additionally, a gain circuit adjusts the signal sent to the position compensator to account for misclamping and imperfections in the data disk. The position compensator features a tilt circuit that compensates for any tilting of the disk drive from a non-horizontal position.
