An international team of researchers led by the University of York in England has demonstrated fast data recording on hard drives using heat. They used an ultra-short pulse of heat to reverse the poles in a ferrimagnet in order to write the data. "It was, until now, generally accepted that a directional stimulus must reverse magnetization," University of York scientist Thomas Ostler told TechNewsWorld. "We have now shown that there is something missing in the conventional picture"
