Abstract
L'invention concerne un support d'enregistrement optique comprenant une ou plusieurs couches supports d'information (30). Au moins une de ces couches supports d'information (30) renferme un corps mémoire à variation de phase optique, lequel est constitué d'un alliage à variation de phase optique et d'au moins un élément modificateur ajouté à cet alliage à variation de phase optique, ce qui améliore les possibilités d'effacement dudit support d'enregistrement optique d'au moins 3 dB.
