Today, amorphous semiconductor films of Te-based and Sb-based alloys are utilized for rewritable optical disks, representatively DVD-RAMs. Here, the author will review the phase-change mechanism enabling the fine properties of the present optical disks, such as short laser-crystallization time of several ten nano-seconds and long life over several ten years.
