The reliability of hard drives can be a problem, but not for this model created by a group of scientists to last.
The reliability of hard drives can be a problem, but not for this model created by a group of cienDe According to Science, Patrick Charton, the French agency responsible for managing nuclear waste (ANDRA) presented a solution to the problem of storing information very long term: a sapphire disk in which information is recorded using platinum.
The prototype costs 25 000 euros to make, but Charton says he is able to survive a million years. The goal is to provide information to future archaeologists. However, says: "I have no idea about any language in which to write."
According Science, most countries with nuclear power plants agree that the solution for dealing with nuclear waste which has to be buried is a solution to the problem of information. It is necessary to create a form of information to survive for long periods of time.
The ANDRA in 2010 initiated a project to solve these problems. To this end, brought together experts from various fields of specialties, including materials scientists, archivists, archaeologists, anthropologists, linguists and even artists.
The disc of sapphire is one of the products resulting from this effort. It is made of two thin disks of sapphire industry, with 20 cm in diameter. On one side, to record images with platinum (up to 40,000 thumbnail images), and then fuse the two disks.
