Title: The Innovative Contributions of Andrew Chiu
Introduction
Andrew Chiu is a prominent inventor based in San Jose, California. He has made significant contributions to the field of technology, particularly in magnetic write heads and sensor technologies. With a total of 13 patents to his name, Chiu's work has had a substantial impact on the industry.
Latest Patents
One of Chiu's latest patents is titled "Magnetic write head having spin torque oscillator that is self aligned with write pole." This invention features a magnetic write head with a write pole that has a tapered trailing edge portion. The spin torque oscillator is formed entirely on this tapered edge and is self-aligned with the write pole's sides. This innovative method allows for the self-alignment of the spin torque oscillator during the photolithographic and ion milling process.
Another notable patent is "Multiple-sense thermo-resistive sensor for contact detection of read-write heads." This invention involves detecting a touchdown event between a read/write head and a magnetic disk surface using multiple sensors located at the air-bearing surface. The sensors increase the likelihood of detecting a touchdown event, which occurs when a portion of the head contacts the disk surface. The frictional heat generated during this contact changes the electrical resistance of the sensors, allowing for effective detection.
