Salting hard drives to max capacities to 18TB

Sean Gallagher

Running out of disk space for your movies and music? There’s good news from Singapore. Researchers at the Institute of Materials Research and Engineering have found a way to increase the density of hard disk storage by six times over current drives, all thanks to salt.

While he was a graduate student at MIT, IMRE’s Dr. Joel Yang developed a new electron-beam lithography process which uses sodium chloride to enhance the developer solution. He and his research team at IMRE, in collaboration with researchers from the National University of Singapore and the Agency for Science, Technology, and Research’s Data Storage Institute have refined the process, and have been able to fabricate magnetic storage media with a density of 3.3 terabits per square inch.
