An international team of scientists has demonstrated a revolutionary new way of magnetic recording which will allow information to be processed hundreds of times faster than by current hard drive technology. The researchers 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 York's Department of Physics, are reported in the February edition of Nature Communications. York physicist Thomas Ostler said: "Instead of using a magnetic field to...
