Scientists have developed an optical disc technology that they say can store at least 10 terabytes per disc with a lifetime of over 600-650 years:

"While optical technology can expand capacity, the most advanced optical discs developed so far have only 50-year lifespans," explained lead investigator Min Gu, a professor at RMIT and senior author of an open-access paper published in Nature Communications. "Our technique can create an optical disc with the largest capacity of any optical technology developed to date and our tests have shown it will last over half a millennium and is suitable for mass production of optical discs."

[...] The new nano-optical long-data memory technology is based on a novel gold nanoplasmonic hybrid glass matrix, unlike the materials used in current optical discs. The technique relies on a sol-gel process, which uses chemical precursors to produce ceramics and glass with higher purity and homogeneity than conventional processes. Glass is a highly durable material that can last up to 1000 years and can be used to hold data, but has limited native storage capacity because of its inflexibility. So the team combined glass with an organic material, halving its lifespan (to 600 years) but radically increasing its capacity.

Also at RMIT University.

    Sino-Australian technology.

    The Aussie scientist may have helped figure it out, but I seriously doubt that they can pull together the economic efficiency down-under to actually make these things in volume for the world market.

    yeah, well, american technology, ozzie technology, all made in china.

      Hey, at least we still make (some) decent movies...

    With China's help we can... much smaller countries in Asia have achieved similar with China's help

      So, Chinese owned businesses in Australia - employing Australian workers? Yeah, that might work - it works for German car makers in the US Southeast.

      What do you think is the major impediment to Australian/US owners being able to compete here? Raw capital is certainly one problem, but there also seems to be an issue with management style...
