Recording by heat pulses

An international team of researchers at the University of York had discovered a new and revolutionary way of magnetic recording that can transfer up to 200Gbps, more than 300 times the speed of SATA III on hard drives on hard drives with up to 10 times more capacity than the current ones.

The secret behind this new technology lies in a new system of recording by heat pulses. The researchers found that they could record data using only heat, applying ultrashort heat pulses with a laser, changing North-South magnetic orientation of magnetic nanoparticles pairs.

Consecutive heat pulses change the North-South orientation to South-North, which can be perfectly translated into zeros and ones and be used as storage system.

They claimed that this discovery will not only make future magnetic recording devices faster, but more energy-efficient too, since it could be developed a method to use the heat emitted by other components.
