Title: Bong Jin Lee: Innovator in Hard Disk Drive Technology
Introduction
Bong Jin Lee is a notable inventor based in Fremont, CA (US). He has made significant contributions to the field of hard disk drive technology, holding a total of 2 patents. His work focuses on improving the performance and reliability of hard disk drives, which are essential components in modern computing.
Latest Patents
One of Bong Jin Lee's latest patents is titled "Equalization and minimization of multi-head stack assembly's motion during self servo writing and HDD operation." This invention describes a hard disk drive that includes a spindle motor and an actuator arm coupled to a base plate. A plurality of disks are coupled to the spindle motor, and a plurality of heads are coupled to the actuator arm and the disks. The drive also features a cover attached to the base plate, enclosing a hard disk area that has a horizontal center line. The air space within the hard disk area is equal and symmetrical in a vertical direction, which helps reduce track mis-registration when servo is copied from one disk surface to another.
Another significant patent by Bong Jin Lee is "Silent retract of heads in a hard disk drive." This invention involves a hard disk drive with an actuator arm assembly that is coupled to a head and includes a voice coil motor. The drive circuit provides a drive current to the voice coil motor to move the actuator arm assembly into contact with a magnet. By limiting the amplitude and changing the pulse widths of the drive current as the actuator arm approaches the magnet, this invention reduces any audible noise associated with retracting the heads.
