Title: Innovations by Jae-hyuk Han
Introduction
Jae-hyuk Han is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of hard disk drive technology, holding a total of 6 patents. His work focuses on enhancing the reliability and performance of data storage devices.
Latest Patents
One of his latest patents is for a hard disk drive adapted to detect free-fall and perform emergency parking of the read/write head prior to impact. This innovative design includes a spindle motor, an actuator, a static eccentricity sensor, a monitor, and a central controller. The spindle motor rotates a disk, while the actuator moves the read/write head over the disk. The static eccentricity sensor measures static eccentricity associated with the rotary body, and the monitor generates a free-fall signal when it detects that the HDD is in a free-fall state. The central controller then initiates an unloading/parking operation for the read/write head in response to this signal.
Another notable patent involves a fluid dynamic bearing and a hard disk drive employing the same. This fluid dynamic bearing is designed to stably support a rotating body subjected to non-uniform forces. It includes a journal bearing part that supports a rotary shaft radially, a thrust part at one end of the rotary shaft, and a thrust bearing part that supports the rotary shaft longitudinally. The design features multiple grooves on the surface of the thrust bearing part, enhancing its performance.
