An international group of researchers has shown that the use of graphene in hard disks allows you to increase the amount of memory 10 times compared with modern drives.

The first hard drives appeared in the middle of the last century, and since then gradually their size decreased, and the amount and density of stored data increased. The principle of their work is still based on rapidly rotating plates, which mobile magnetic head records data. From wear and damage, modern plates protect the coating on a carbon basis, which occupies a significant proportion of space.

Now scientists led by the team from the University of Cambridge presented a new technology of ultra-high density hard disks. As a drive, they took plates from iron-platinum coated from graphene 1-4 thickness of an atom, which allowed to reduce friction, reduce mechanical wear and corrosion 2.5 times, as well as reduce the space between the plates.

Further, the researchers experienced a new thermal magnetic record technology (HAMR) created by the hard disk, which increases the storage density due to the high temperature, destructive for the modern protective layer. As a result, they achieved a tenfold increase in information recording density (up to 10 terabytes per square inch).
