A new method of magnetic recording was demonstrated by an international group of scientists. It could allow hard drives to transfer data manifolds faster than currently possible with the given technology according to a report on The Verge. The scientists found that they could record information using only heat, which was considered impossible by earlier researchers. A physicist from the University of York, Thomas Ostler, said that the new method transfers data at the speed of terabytes per second.
Not just that, but on top of it all, it uses less energy than other conventional known systems utilizing magnetic fields. Through this method the positions of North and South poles of a magnet could be inverted by a brief heat pulse that gathered energy from stronger internal forces of magnetic media.
Further details of the research can be found in the February edition of Nature Communications. But this is as yet a science laboratory experiment only. There is no certainty that it could be brought to the benefit of the general public as yet. Because it is still undetermined whether this technology will be available in future computers and with the consumerism on the rise, the new developments in tech can only be used if it benefits the market.
