Title: Nathaniel Curran Brandt: Innovator in Heat-Assisted Magnetic Recording Technology

Introduction

Nathaniel Curran Brandt is a notable inventor based in Saint Paul, MN (US). He has made significant contributions to the field of heat-assisted magnetic recording (HAMR) technology. His innovative work focuses on improving the stability and efficiency of data recording processes.

Latest Patents

Brandt holds a patent for an "NFT back reflection monitor for heat-assisted magnetic recording head." This invention discloses methods and configurations for monitoring reflections in HAMR heads that may lead to laser instability and power variation. The HAMR heads direct light emitted by a laser toward a near field transducer (NFT) to produce plasmons that assist in data recording. A certain amount of the laser light may be reflected at or near the NFT back toward the laser, which can cause laser instabilities over time. To address this issue, a back reflection monitor is utilized to detect the intensity of a portion of the reflected light. This monitoring capability may be integrated into HAMR recording head assemblies, along with optical components and electrical circuitry that provide laser light transmission monitoring capability.
