Heat-assisted magnetic recording (HAMR) media status, requirements, and challenges to
extend the areal density (AD) of magnetic hard disk drives beyond current records of around …

A write head design consisting of a split pole and a gapped near-field transducer is
presented. Through simulation, we found our design can produce a maximum effective cross …

Differences in the areal density capability limits for heat-assisted magnetic recording
(HAMR) and conventional perpendicular magnetic recording (PMR) are explored using …

Near the Curie temperature, the anisotropy field of magnetically uniaxial L1 0 FePt is
expected to follow the scaling law (1–T/T c) β, where T is the temperature and T c is the …

We investigate a tapered, hybrid plasmonic waveguide which has previously been proposed
as an optically efficient near-field transducer (NFT), or component thereof, in several devices …

In this work we present recording data taken on a spin-stand using Heat-Assisted Magnetic
Recording (HAMR) components. In HAMR, the laser current (applied to assist writing onto …

We introduce a theoretical and experimental framework that enables quantitative
measurements of the temperature and magnetic field profiles governing the thermo …

As cloud computing and massive-data machine learning are applied pervasively, ultra-high
volume data storage serves as the foundation block. Every day, nearly 2.5 quintillion bytes …

The edge gradient of the thermal spot used to define bits in heat-assisted magnetic
recording is a critical parameter in determining the quality of the magnetic transitions. We …

To provide useful component design guidance, micromagnetic simulations of heat-assisted
magnetic recording (HAMR) must include estimates of the areal density (AD) of the …
