Abstract

The reflectivity of the phase-change media of optical recording changes slightly upon the application of a weak laser pulse (i.e., a pulse of insufficient power to write/erase a mark), returning to its initial value at the end of the pulse. This behavior is shown to be due to the temperature-dependence of the optical constants of the phase-change layer.
