HDDs could become 100x faster
Drives using the technology will be hundreds of times faster than previous drives, say University of York researchers - able to record thousands of gigabytes per second.
The researchers found they could record information using only heat -previously unimaginable.
York physicist Thomas Ostler said: '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.'
Modern magnetic recording technology employs the principle that the North pole of a magnet is attracted to the South pole of another and two like poles repulse.
Until now it has been believed that in order to record one bit of information
