Title: Hieu Lam: Innovator in Magnetic Recording Technology
Introduction
Hieu Lam is a prominent inventor based in Milpitas, California, known for his significant contributions to the field of magnetic recording technology. With a total of 11 patents to his name, Lam has made remarkable advancements that have influenced the industry.
Latest Patents
One of Hieu Lam's latest patents is titled "Perpendicular magnetic recording write head with main pole formed on a metallic amorphous underlayer." This invention features a main pole typically made of CoFe, electroplated into a trapezoidal-shaped alumina trench. The design includes a metallic side gap layer that adjusts the trench width to achieve the desired main pole dimension. A nonmagnetic metallic amorphous underlayer, preferably an amorphous NiTa or NiNb alloy, is deposited on the side gap layer. This underlayer enhances the growth between the side gap layer and the pole seed layer, resulting in improved magnetic properties for the main pole.
Another significant patent is the "Method and system for magnetic recording media." This invention describes a patterned magnetic recording media where the recording layer consists of a continuous surface of more-noble and less-noble elements. The method involves masking the recording layer to shield areas for recording domains while exposing areas in between. A voltage bias establishes the substrate as an anode, allowing for controlled removal of less-noble elements, which minimizes oxidation and enhances the quality of the recording domains.
