From TechOn!:

"Japanese researchers prototyped a memory system that can store large volumes of data for more than a thousand years. The system, "Digital Rosetta Stone (DRS)," was announced June 16, 2009, by Keio University, Sharp Corp and Kyoto University at the 2009 Symposium on VLSI Circuits, which is taking place in Kyoto, Japan (lecture number: C3-3). They stacked wafers mounted with mask ROM and packaged it with SiO₂. Power supply and signal communication are conducted by wireless."

Very, very cool... but there remains the issue of transparency. If someone finds this disk 1,000 years from now, how will they know how to access the information? We think a microetched instruction manual might do very nicely.
