Heat-based recording speeds hard drives

A new method of recording information to hard drives could increase their speed by hundreds of times.

An international team has found, astonishingly, that it's possible to record information using only heat – making future magneticrecording devicesnot only faster, but more energy-efficient too.

"Instead of using a magnetic field to record information on a magnetic medium, we harnessed much stronger internal forces and recorded information using only heat," says University of York physicist Thomas Ostler.
