Amar Nath

Title: Amar Nath and Disk Servo-Writing Innovation.

Introduction

Amar Nath is an inventor associated with Pathum Thani, Thailand, and Western Digital Technologies, Inc. His patent work addresses a manufacturing challenge in disk-drive production: reducing fly height modulation during servo writing.

Latest Patents

The available information lists one patent for Amar Nath: “Adjusting Rotation Speed of Disk to Reduce Fly Height Modulation When Servo Writing in Gas.” The disclosed method injects gas into a head disk assembly and rotates the disk while a head reads data. The resulting signal is used to measure the head’s fly height modulation. If that modulation exceeds a threshold, the disk’s rotation speed is adjusted before servo writing.

After servo writing, the gas is evacuated from the assembly. The disk is then rotated at a normal speed, lower than the adjusted servo-writing speed, and manufacturing data is written. This approach uses different rotation speeds for servo writing and subsequent manufacturing operations.

Career Highlights

Nath’s listed patent connects his inventive work with disk-drive manufacturing at Western Digital Technologies, Inc. The invention focuses on controlling operating conditions during servo writing to address fly height modulation.

Collaborations
