A more accessible approach than the High-Density Rosetta might be the M-DISC.[0] It's essentially a DVD/Blu-Ray which materials engineered to last significantly longer than standard ones. I attended a chemistry lecture by Prof. Matthew Linford (BYU) and from the gist of his description,[1] the materials that they were using have a good shot at lasting 500 to 1000 years if properly stored.
