Heat-assisted magnetic recording (HAMR) limitations and extendibility are studied in light of
the recent 1.0 Tb/in 2 technology demonstration. The paper examines HAMR specific …

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

We calculate jitter of the signal from transitions written on Voronoi-pattern media and played
back with readers of varying widths. The expected dependence of jitter on reader width, as …

In order to achieve higher areal density, magnetization transition width must be reduced.
This requires small media switching field distribution (SFD). Here we explore SFD and …

The understanding of measured jitter is improved in three ways. First, it is shown that the
measured jitter is not only governed by written-in jitter and the reader resolution along the …

The effect of a 1.5 nm thick CoX layer (CAP) of high Curie temperature TC, deposited on top
of an L1 0 Fe 50 Pt 50 layer (MAG) on the properties of the MAG/CAP bilayer is investigated …

In magnetic recording the signal-to-noise ratio (SNR) is a good indicator for the quality of
written bits. However, a priori it is not clear which parameters have the strongest influence …

The signal-to-noise ratio (SNR) of a bit series written with heat-assisted magnetic recording
on granular media depends on a large number of different parameters. The choice of …

Micromagnetic simulation is used to calculate the temperature derivative of the switching
field d H sw/d T for a composite media with a superparamagnetic writing layer. The results …

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 …
