Title: Innovations by Debashish Tripathy in Heat-Assisted Magnetic Recording

Introduction

Debashish Tripathy is a notable inventor based in San Jose, CA, who has made significant contributions to the field of heat-assisted magnetic recording (HAMR). With a total of three patents to his name, Tripathy's work focuses on enhancing the performance and efficiency of magnetic recording media.

Latest Patents

One of Tripathy's latest patents is for a soft underlayer (SUL) designed for heat-assisted magnetic recording media. This SUL possesses characteristics that make it compatible with the high-temperature requirements associated with HAMR media growth and writing, specifically at temperatures exceeding 500°C. The SUL features a high crystallization temperature of over 450°C and a high Curie temperature greater than 300°C. It can maintain a saturation magnetization value exceeding 9 kGauss at elevated temperatures, remaining amorphous up to 650°C while exhibiting a relatively flat integrated noise profile from approximately 300°C to 650°C.

Another significant patent involves a HAMR medium that includes a bi-layer, which enables the use of a thinner heat-sink layer. This innovation allows for a reduced operating current of a laser during write operations while maintaining comparable performance parameters to traditional HAMR media that utilize a thermal-barrier layer and a thicker heat-sink layer. Additionally, this patent describes a HAMR data-storage device that incorporates the HAMR medium within a HAMR disk, along with a method for producing the HAMR medium.
