Title: Yiming Wang: Innovator in Write Head Designs

Introduction

Yiming Wang is a prominent inventor based in San Jose, California, known for his significant contributions to the field of data storage technology. With a total of 10 patents to his name, Wang has made remarkable advancements in write head designs that enhance data recording capabilities.

Latest Patents

Wang's latest patents include innovative methods for forming write head designs with sandwich trailing shields (STS) for high data rate perpendicular recording. One notable patent describes a method of forming a PMR writer with an all wrap around (AWA) shield design. This design incorporates leading shields, side shields, and trailing shield structures that utilize an alloy with a damping parameter α of ≥0.04. This innovation minimizes wide area track erasure (WATE). The trailing shield structure consists of two outer magnetic layers with an 8-16 kiloGauss (kG) saturation magnetic moment (Ms) on each side of a center stack, which features a lower write gap, a middle hot seed layer (Ms of 19-24 kG), and an upper magnetic layer (Ms of 16-24 kG). The combination of the hot seed layer and upper TS magnetic layer promotes improved area density capability (ADC). Additionally, a second TS layer with Ms of 16-24 kG may be formed on the upper magnetic layer, further enhancing the design's effectiveness.
