Latest Patents

Hua Yuan's most recent patents include:

1. **Magnetic Recording Medium with Underlayer Configured to Reduce Diffusion of Titanium into a Magnetic Recording Layer**

This patent describes various apparatuses, systems, methods, and media for creating a heat-assisted magnetic recording medium. It features a magnetic recording layer positioned on a magnesium oxide-titanium oxide (MTO) underlayer, which has an additive material that chemically bonds with titanium. The use of this additive material, such as iron-oxide, iron, carbon, or various aluminum oxides, results in less diffusion of titanium into the magnetic recording layer, enhancing the recording layer's performance and areal densities. Additionally, an extra magnesium oxide-nitrogen underlayer may also be included.

2. **Heat Assisted Magnetic Recording Media with Amorphous Magnetic Grain Boundary Material**

This patent aims to improve signal-to-noise characteristics by reducing the Curie temperature distribution in HAMR media structures. The described magnetic recording medium includes a substrate, a heat sink layer, and a magnetic recording layer containing multiple magnetic recording grains made from a first magnetic alloy. Moreover, segregants made from a second magnetic alloy, which has a higher Curie temperature than the first, are implemented to isolate the recording grains and optimize the medium's performance.
