Introduction

Do-Soo Lee is an inventor associated with Suwon, South Korea, and Samsung Electronics Co., Ltd. His listed work includes 3 patents focused on disk-drive control and operation.

Latest Patents

Lee’s listed patents address stabilizing track jumps and controlling sled velocity in disk drives.

“Track jump stabilizing method of disk drive” describes a method for preventing an objective lens from bumping against the sled wall during a track jump. The method coordinates tracking and sled movement while counting track zero crossings until a predetermined count is reached.

“Method and circuit for uniformly controlling sled velocity of a disk” describes circuitry that measures sled velocity, converts sensor signals, selects and maintains a maximum voltage-variation value, and adjusts the drive signal. The approach is designed to control sled movement while minimizing power consumption.
