IBM Discovers How to Store Data in a Dozen Atoms

Researchers at IBM’s Almaden Labs have created a 12-atom magnetic memory bit, in a continuation of work on atomic-level memory storage first posited in 1959 by American physicist Richard Feynman. Disk drives currently use about 1 million atoms to store a single bit of information, according to IBM. The scientists used antiferromagnetism to achieve their result. They stored the ASCII code for the word “Think” on 96 iron atoms using this approach.
