Title: Huanqin Guan: Innovator in Magnetic Recording Technologies

Introduction

Huanqin Guan is a notable inventor based in Milpitas, CA, specializing in advanced magnetic recording technologies. He has made significant contributions to the field, particularly through his innovative patent that enhances heat-assisted magnetic recording (HAMR) mediums.

Latest Patents

Huanqin Guan holds a patent for "Magnetic recording media with high magnetization absorption layer and gradient segregant structure." This invention discloses various apparatuses, systems, methods, and media designed to provide a HAMR medium that incorporates a Co-rich Pt-doped capping material alongside a CoFe-based absorption layer. The absorption layer is characterized by a higher magnetization than the capping layer, and both layers contain segregants such as BN, SiO, BO, and ZrO. Notably, the volume percentage of segregants in the absorption layer exceeds that in the capping layer by 5% to 15%, creating a gradient in segregant percentage. Additionally, the absorption layer may consist of two sub-layers, with the upper sub-layer containing a greater volume percentage of segregants than the lower sub-layer, further enhancing the gradient. An etching process using a sacrificial layer is also applied to the absorption layer to minimize head-to-media spacing.
