Physicists say they have developed a way to use lasers to accelerate storage and retrieval of data on hard drive by up to 100,000 times.
In a study published in the specialist journal Nature Physics, a team led by Jean-Yves Bigot of the Institute of Materials Physics and Chemistry in Strasbourg employed a "femtosecond" laser, using ultra-fast bursts of laser light, to alter electron spin and thus speed up retrieval and storage. "Our method is called the photonics of spin, because it is photons [particles of light] that modify the state of the electrons' magnetisation" on the storage surface.
