A revolutionary new way of magnetic recording uses heat to allow data to be processed hundreds of times faster than current hard drive technology
An international team of scientists found they could record information using only heat a previously unimaginable scenario.They believe this discovery will not only make future magnetic recording devices faster,but more energy-efficient too.
The results of the research,which was led by the University of Yorks Department of Physics,are reported in the journal Nature Communications.
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.This revolutionary method allows the recording of Terabytes (thousands of GB) of data 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, said York physicist Thomas Ostler.
The multinational team of scientists included researchers from Spain,Switzerland,Ukraine,Russia,Japan and the Netherlands.Experimental work was carried out at the Paul Scherrer Institut in Switzerland,the Ioffe Physical Technical Institute of the Russian Academy of Sciences and Radboud University Nijmegen,Netherlands.
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 ultra short heat pulse,harnessing the power of much stronger internal forces of magnetic media.
