Title: Young-Ok Goh: Disk-Drive Control Inventions.

Introduction

Young-Ok Goh is an inventor associated with Suwon, South Korea, and Samsung Electronics Co., Ltd. The supplied information credits Goh with 3 patents and describes work on disk-drive mechanisms and control systems.

Latest Patents

One of Goh’s listed inventions is “Track Jump Stabilizing Method of Disk Drive.” It describes a method for preventing an object lens from bumping against a sled wall while a disk drive moves between tracks. The method coordinates sled movement and tracking, counts track zero crossings, and repeats the control steps until a predetermined count is reached.

Another listed invention is “Method and Circuit for Uniformly Controlling Sled Velocity of a Disk.” Its circuit converts speed-sensor signals into values used to regulate sled velocity. It selects and maintains a maximum voltage-variation value, adjusts the control signal through inversion and subtraction, and applies the result to the drive circuit to help minimize power consumption.

Career Highlights

The described inventions focus on improving disk-drive operation through precise track-jump stabilization and consistent sled-velocity control. Together, they address mechanical interference, motion regulation, and power use.

Collaborations

The supplied information identifies Do-Soo Lee as Goh’s coworker. It does not specify whether Lee collaborated on either of the listed inventions.

Conclusion

Young-Ok Goh’s listed patent work at Samsung Electronics centers on practical disk-drive control, including stable track access and efficient sled movement.
