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.
Computer hard drives could suddenly become far faster, thanks to a new technology that uses heat to write information to the magnetic storage systems.
The technique uses heat to write to the magnetic storage system, instead of magnetic fields. It's far faster and uses less energy
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.'
The technology uses ultra-short heat pulses to change the magnetism of material in the drive, allowing for far faster drives.
'This revolutionary method allows the recording of Terabytes - thousands of gigabytes - of information per second, hundreds of times faster than present hard drive technology.
As there is no need for a magnetic field, there is also less energy consumption.'
The technique uses ultra-short pulses of heat to write information to hard drives, rather than magnetic fields
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 – by inverting the poles of a magnet – there was a need to apply an external magnetic field.
The stronger the applied field, the faster the recording of a magnetic bit of information.
However, the team of scientists has demonstrated that the positions of both the North and South poles of a magnet can be inverted by an ultrashort heat pulse, harnessing the power of much stronger internal forces of magnetism. ( dailymail.co.uk )
