Heated Hard Drives Could be Super-Quick
Physicists have discovered a new way to record data that could make future hard drives hundreds of times faster than existing technology - all you need is a little heat. Hard drives store data using magnetic recording, with tiny sections of the disc magnetised in a particular direction to represent the 0 or 1 of a bit. Recording data involves flipping the direction, which is currently done using an external magnetic field. Now, a team of researchers led by Thomas Ostler at the University of York, UK have discovered that a short burst of heat can do the job much faster.
