Title: Keung Youn Cho: Innovator in Hard Disk Drive Technology
Introduction
Keung Youn Cho is a prominent inventor based in San Jose, CA, known for his significant contributions to hard disk drive technology. With a total of 10 patents to his name, Cho has made remarkable advancements in the field, particularly in methods for data erasure and recording head design.
Latest Patents
One of Cho's latest patents is titled "Self-spinning disk bulk erasure for hard disk assembly." This innovative method involves moving a hard disk drive adjacent to an erasure head that emits a magnetic field. The combination of the magnetic field and the movement of the hard disk drive generates a Lorentz force, causing the disk to spin. This process effectively erases the entire disk without activating the spindle motor, thereby eliminating any Faraday coupling from the erasure head into the motor.
Another notable patent is the "Dual write gap perpendicular recording head with a non-magnetic backside shield." This design features a non-magnetic backside shield that minimizes the flow of backside flux through the head. The fabrication process includes forming a non-magnetic backside shield layer on a main pole, followed by the creation of a tapered pole portion and the addition of a non-magnetic write-gap layer and write shield.
