"'The volume of data being created every day is exploding, but in terms of keeping it for later generations, we haven't necessarily improved since the days we inscribed things on stones,' Hitachi researcher Kazuyoshi Torii told AFP. 'The possibility of losing information may actually have increased,' he said, pointing out that CDs and tape storage are predicted to last less than a few decades at best, and in many cases fail within years."
Hitachi has therefore proposed a new storage medium: quartz glass. They argue that data lasered in binary formatted dots on the glass in four layers can be stored at 40MB per square inch. And unless the glass is broken, the data will last hundreds of millions of years in the glass. In addition, since the dots can be read using a simple microscope, future readers of the data should be able to decipher it even if technology has changed drastically.
We like being reminded that no matter how advanced technology gets, some of the core problems, like physical materials to store data in, can still be solved by 'basic' glass and dots.
