Beschreibung
Zusammenfassung:	An optical data recording and storage medium including at least one reflective layer formed from a copper alloy that contains, in addition to copper, about 0.1 to about 3.0 wt. %, based on the total weight of alloy, of samarium (Sm) and may further include from about 0.1 to about 5.0 wt. % titanium (Ti). L'invention concerne un support de stockage et d'enregistrement de données optiques comprenant au moins une couche réfléchissante constituée d'un alliage de cuivre contenant, en plus du cuivre, environ 0,1 % à 3,0 % en poids, en fonction du poids total de l'alliage, de samarium (Sm) et également environ 0,1 % à environ 5,0 % de titane (Ti).
