Data storage speeds up by a factor of 1000
Researchers at Eindhoven University of Technology and the FOM Foundation have recently presented a new technology that potentially allows data to be stored 1,000 times faster with ‘spin current’ using ultra-short laser pulses.
Data is conventionally stored using magnetization, making bits 1 or 0, but the limits of this technology have been reached, and researcher Sjors Schellekens of the Technical University of Eindhoven says that it’s time for new data storage technology.
The ‘spin current’ is able to cause a change in magnetization, which is 1,000 faster than what is possible with today’s technology. The new method has also been hailed as step towards future optical computer chips, which Eindhoven University of Technology is now working on thanks to a Dutch grant of close to 20 million euro.
In 2009 The University of Twente was on to something in the same field with spin polarisation achieved at room temperature, which also sped up the reading of a hard disk.
