Ultra-high density hard disk drives or hard disk drives, call them whatever you like, are hard disk drives. These devices can be made of graphene, increasing storage capacity ten times compared to HDs with current technology. At least, that’s what researchers at the Cambridge Graphene Center note.
Graphene HDDs are nothing new. They first appeared in the 1950s, but their use as storage devices in personal computers only grew three decades later. Years passed and devices became smaller and more dense.

The upper layers of hard drives consist of plates and a head as the main components, and are currently made of a carbon base (COC). This protects the panels from mechanical damage and corrosion. With smaller thicknesses, they provide more disk space.
This is how the researchers multiplied space by ten when using graphene. They replaced the commercial carbon layers with four graphene and tested friction, wear and tear, thermal stability, and lubricant compatibility.
Thinner than the previous material, graphene still meets the properties required for the upper layer of a hard disk drive. Carbon nanomaterial protects against wear (2.5 times less), has low friction (two times less), wear resistance, hardness, lubricant compatibility and surface smoothness.
The researchers even transferred graphene to iron-platinum hard drives as a magnetic recording layer and tested heat-assisted magnetic recording (HAMR). Oral contraceptives in current devices do not work at high temperatures. Yes, graphene.
With this nanomaterial, more than 10 terabytes per square inch can be stored. “This will drive the development of new high-density hard drives in the region,” said Anna Ott, co-author of the study and a member of the Cambridge Graphene Centre.
In addition to Cambridge Graphene Center scientists, teams from the University of Exeter, as well as in the United Kingdom, India, Switzerland, Singapore and the United States, participated in the study. The research was published in an article in Scientific journal Nature Connections.
