Hi, I recently watched part (the end) of a technology programme on CNN or the BBC. It was about a new fascinating, revolutionary "sci-fi" technology of "etching" an unbelievable amount of data onto an "indestructable glass(?) carrier. The segment was too short, so I can't be more specific. Has anyone heard of it and knows the precise term for this new technology? Have not been able to find anything on Google. Thanks!
