Though hard disk drive technology has improved in late clock time , you ’d be a brave soul indeed to use one for more than a duad of years without back it up . But now a squad of scientists has made a hard magnetic disc from sapphire which it claims will last 1 million age — just do n’t look to be capable to afford it .
The task was born when atomic waste depositary realized they necessitate to preserve record of where they ’d buried waste not just in the near - futurity , but for tens of thousands of years . presently , there ’s no digital format that we know can last that long with certainty .
Which is why a team from the waste management agency ANDRA has commissioned the ultimate HDD : a lazuline disk inside onto which information is grave using Pt . Made from two thin disks of industrial sapphire , the matter measure out about 20 centimeters across , reports Science .
data point is etched in platinum onto one side of one of the magnetic disk , before the other is commit on top to shape an data sandwich . Then , the disks are molecularly mix together . So far , the hardware has been bury in acid to try its durability and to simulate ripening . The researchers , as a effect , hope the thing could make it at least 1 millions years .
There are just two little job . First , the prototype be a cool $ 30,000 dollars . secondly , how do you communicate information to someone who might need to read it in tens of thousands of years ? In fact , the researchers openly admit that they “ have no approximation what oral communication to write it in ” . How about pictures instead ? [ Science ]
