Using synchrotron radiation at SPring-8—a large-scale synchrotron radiation facility—Tohoku University, Toshiba Corporation, and the Japan Synchrotron Radiation Research Institute (JASRI) have successfully imaged the magnetization dynamics of a hard disk drive (HDD) write head for the first time, with a precision of one ten-billionth of a second. The method makes possible precise analysis of write head operations, accelerating the development of the next-generation write heads and further increasing HDD capacity. Details of the research were published in the Journal of Applied Physics on October 6 and presented at the 44th Annual Conference on Magnetics in Japan, on December 14.
