If you are still impressed by the capabilities offered by hard disks, prepare to be surprised. Indeed, scientists from IBM and CFEL (Center for Free - Electron Laser Science) of Hamburg came to create the smallest unit of storage magnetic in the world.
Its creation required that 12 atoms to store a bit or 96 atoms for a byte, at the time or hard disks use on average half a billion atoms to ensure the registration of a byte.
This major innovation could reduce the size of storage media, while offering even more advantageous capabilities. The developed Nano-memory is only 4 x 16 nanometers, which represents a density 100 times greater than that of a hard disk.
To store information, researchers were able to use the antiferromagnetism, namely a kinetic movement of neighbouring atoms in opposite directions from those of the Ferromagnetism used in our current hard drives. Also, the unit becomes neutral, which allows to have the elements of storage at closer distances: only 1 nanometer.
Rest to see the progress of this project, and his involvement in future storage media.
