Carbon nanotubes have found another application. A few days ago, an article was published in the journal Nature Scientific Reports, which for the first time discusses the possibility of using multi-walled carbon nanotubes (MWCNT) in magnetic recording on hard drives. These are various complex CNT structures in the form of 'matryoshkas', 'coils', and other designs. The task in all cases comes down to one thing - to fill each such complex carbon nanotube with magnetic nanoparticles. Individual magnetic nanoparticles will not provide data recording effects. The magnetization can only be changed in a whole tube, but it will still be denser than recording magnetically. dom\u00e9na<\/a> b\u011b\u017en\u00e9 magnetick\u00e9 desce HDD.

The specialist notes that existing methods for increasing the recording density on HDDs no longer meet the speed of data growth. To curb data growth, it is necessary for the storage density on hard drives to increase by 40% each year, while in recent years it has been growing by 10-15% annually. Recording using carbon magnetic tubes could be the response to the challenges of the information age, but a colossal amount of research work still lies ahead.<\/p>\n
