The concept of phase-change recording is straightforward. An intense laser or current pulse heats and melts the crystalline material, which is subsequently quenched into the amorphous state.

This latent heat can store a significant amount of energy in a material over a relatively small temperature change. This latent heat exists in solid-to-liquid phase changes as well, where it’s ...
