New hard disk write head analytical technology can increase hard disk capacities

Using synchrotron radiation at SPring-8 - a large-scale synchrotron radiation facility - researchers 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.
