Manufacture techniques of optical disc media for long-term data storage are considered. As demonstrated, the use of sapphire substrates allows creating media with the predicted data-storage term of thousands of years. Techniques for nanostructured relief forming on high-stable material surface are studied. Experimental results for process of data recording on optical disks with sapphire substrates are presented.
