Title: Innovations in Magnetic Recording Media by Inventor Kai Tang

Introduction

Kai Tang, an esteemed inventor residing in San Jose, CA, has made significant contributions to the field of magnetic recording technologies. With an impressive portfolio of 42 patents, Tang is recognized for his groundbreaking innovations that enhance data storage capacity and efficiency.

Latest Patents

Among his latest contributions, two patents stand out. The first patent relates to a magnetic recording medium featuring a dead magnetic layer. This unique design incorporates a rigid substrate, an amorphous soft magnetic underlayer (SUL), and a dead magnetic layer. The dead magnetic layer is specifically configured to create an interdiffusion region that boosts the tracks per inch (TPI) without causing a significant drop in bits per inch (BPI). This advancement leads to a net increase in areal density capacity (ADC), setting a new standard for recording mediums lacking the dead magnetic layer.

The second notable patent introduces a magnetic recording medium with a tungsten (W) pre-seed layer. This pre-seed layer exhibits higher conductance compared to traditional chromium titanium (CrTi) pre-seed layers. By utilizing a W pre-seed layer composed of approximately 95 atomic percent or more of tungsten, the electrical resistivity decreases, allowing for a reduced thickness without compromising recording performance. The innovations fostered by Tang in these patents significantly enhance magnetic recording technologies.

Career Highlights

Throughout his career, Tang has worked with prominent companies in the technology sector, including Hitachi Global Storage Technologies and Western Digital Technologies.
