Deskripsi
The main limitation to the areal storage density of hard disk drives (HDDs) is the thickness of carbon overcoats protecting the disk media. Here, <2-nm-thick graphene overcoats with improved corrosion, wear and irradiation resistance are shown to meet the requirements for the realization of 4–10 Tb/in2 HDDs with heat assisted magnetic recording.
