The study may open up new opportunities for using light and magnetism to create next-generation information storage devices. The authors note that novel approach produces much less heat (less than 6 joules per cubic centimetre) than today’s hard-disk drives or flash memory. The recording event is also extremely fast, requiring fewer than 20 picoseconds to complete.
