Graphene can increase the capacity of existing hard drives 10 times16 октября, 2021
About the big step or even jump forward reports scientists from the United States. Using the miracle material of the XXI century graphene, they found the ability to increase the range of operating temperatures for hard drives, and at the same time in an unprecedented amount to increase the data density.
In the hard disk, the data is written on fast rotating plates with a moving magnetic head. A special carbon layer protects the plates from mechanical damage and corrosion, however, it requires a certain temperature mode, and these layers increase the volume of the device,
However, it turned out to be more interesting that the use of graphene increases the operating temperature of the hard disk. Scientists applied advanced thermomagnetic record technology (HAMR), which heats the recording layer to a higher temperature and can significantly reduce the size of the magnetic area storing 1 bit of information. Stable remains stable, such a disk becomes more capacious.
The technology of the thermomagnetic record is not compatible with modern protective coatings, but graphene is an exception. The combination of his qualities, as confident Cambridge scientists, makes it possible to achieve the increase in the density of the data in existing hard drives (with the same plates) to 10 TB per square meter. Inch, that is, ten times more than that of modern solutions without the use of protective layers from graphene.
