This is future chatter of course but computer hard drives could suddenly become far faster, thanks to a new technology that uses heat to write information to the magnetic storage systems, instead of magnetic fields. 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
