Title: Innovations of Inventor Hua Han
Introduction
Hua Han is a notable inventor based in Fremont, CA, who has made significant contributions to the field of information storage systems. With a total of 2 patents, his work focuses on enhancing the performance and durability of storage media through innovative materials and methods.
Latest Patents
Hua Han's latest patents include advancements in silicon carbide overcoats for information storage systems and durable landing pads for air-bearing sliders. The first patent describes a silicon carbide (SiC) overcoat that is hard, dense, and durable, eliminating the need for an interlayer to promote adhesion to underlying magnetic or ceramic layers. This innovation reduces head-media spacing, thereby increasing areal storage density and resolution. The SiC overcoat formation process is designed to penetrate less into underlying magnetic layers, further optimizing the spacing of active elements. In an alternative embodiment, SiC can serve as an interlayer for a carbon overcoat, allowing for a thinner design while maintaining the desired surface properties. The second patent focuses on durable landing pads for slider air-bearing surfaces, formed from tetrahedral amorphous carbon (t-aC) using filtered cathodic arc deposition. This method ensures that the pads are extremely hard and highly stressed, with the potential for additional stress-relieving materials to enhance performance.
