German scientists have found a way to increase the capacity of hard drives by 20 times
The new development of scientists from the University of Hamburg is still operating in laboratory conditions and it is too early to talk about its mass implementation.
Currently, in hard drives, storage of information is carried out on the so -called domains – pressure areas on a round plate. When the size of domains decreases to increase the density of information, this leads to the fact that the magnetic field on the parts of the plate surface takes the same direction and orientation as neighboring areas.
German scientists offer to use instead of domains Skirmions, which are swirls created by the group of atoms. They do not interact with “neighbors” and their density can be up to 20 times higher compared to domains.

So far, the new technology is tested in the laboratory, since its functioning requires a temperature of approximately -269 degrees Celsius.
