Title: The Innovative Mind of Pokang Wang

Introduction

Pokang Wang, an accomplished inventor based in San Jose, CA, has made significant contributions to the field of magnetic recording technologies. With a remarkable portfolio of 18 patents to his name, Wang is recognized for his pioneering innovations that enhance data storage methods, particularly in magnetic tunnel junctions.

Latest Patents

Among his latest inventions is the CPP magnetic recording head with a self-stabilizing vortex configuration. This innovative design entails a CPP MTJ or GMR read sensor where the free layer is stabilized by a circumferential vortex magnetization. This configuration allows the pinned layer to maintain a stable magnetization direction parallel to the ABS plane, thus enhancing its overall directional stability. By eliminating lateral horizontal bias layers, typically used in standard designs, Wang achieved the formation of tightly configured shields that effectively protect against side-reading interference.

Another notable patent by Wang involves devices using an addressable magnetic tunnel junction array to identify small superparamagnetic particles. This magnetic sensor is engineered with a regular orthogonal array of MTJ cells located beneath a substrate. When a magnetic field is applied to a particle, it induces a corresponding field within the MTJ cells, leading to detectable resistance changes that reveal the particle's presence. This technique provides a novel means to identify magnetic particles, showcasing Wang's innovative approach to magnetic sensing.
