Storage Density Beyond 10 Tb/in2 Possible For Heat-Assisted Magnetic Recording

A team of physicists have developed simulations that realistically model the heat-assisted magnetic recording write process and found that it could achieve an optimal storage of more than 13 Tb/in2.

The hard disk drives that currently store the majority of the world's data have storage densities of just under 1 Terabit per square inch (Tb/in2). One of the promising technologies being researched for increasing the storage density is heat-assisted magnetic recording (HAMR), which uses lasers to heat individual magnetic grains that are just a few nanometers long. The method requires controlling heat and magnetism on a tiny scale, which has made developing HAMR very challenging.
