Title: Anusha Natarajarathinam: Innovator in Heat-Assisted Magnetic Recording Technology
Introduction
Anusha Natarajarathinam is a prominent inventor based in Bloomington, MN (US). She has made significant contributions to the field of heat-assisted magnetic recording (HAMR) technology. With a total of 2 patents to her name, her work is paving the way for advancements in data storage solutions.
Latest Patents
Anusha's latest patents include innovative methods for forming heat-assisted magnetic recording near-field transducers with heat sinks. The first patent describes a method that involves depositing a near-field transducer on a substrate of a slider. This transducer consists of a plate-like enlarged portion and a peg portion. A first hard stop is formed extending from the near-field transducer to the air bearing surface. A heat sink is then created on the enlarged portion and the first hard stop. Following this, a dielectric material is deposited over the near-field transducer and the heat sink. A second hard stop is placed on the dielectric material, away from the air bearing surface, featuring a recess that corresponds in size and location to the heat sink. The method includes milling at an oblique angle to the substrate between the first and second hard stops to cut through the heat sink. This design enhances the milling rate over the heat sink compared to the dielectric material away from it.
The second patent similarly outlines a method for forming a HAMR NFT heat sink, reiterating the importance of the near-field transducer's structure and the milling process. Both patents highlight Anusha's innovative approach to improving the efficiency and effectiveness of data storage technologies.
