Zusammenfassung:本发明因此涉及含有优选透明的基材的光学数据存储介质,该基材任选已涂敷了一层或多层的反射层和在其表面上施涂光可记录的信息层,任选的一层或多层反射层和任选的保护层或附加的基材或覆盖层,该数据存储介质能够利用蓝光或红光或红外光,优选激光来记录和读,其中信息层含有吸光性化合物和任选的粘结剂。本发明数据存储介质特征在于至少一种杂环偶氮染料用作该吸光性化合物。 An optical data storage medium containing a preferably transparent substrate which has optionally already been coated with one or more reflecting layers and onto the surface of which a photorecordable information layer, optionally one or more reflecting layers, and optionally a protective layer or an additional substrate or a top layer are applied, which data storage medium can be recorded on and read using blue or red light, preferably laser light, wherein the information layer contains a light-absorbing compound and optionally a binder, characterized in that at least one heterocyclic azo dye is used as the light-absorbing compound.
