European researchers are experimenting with storing information within a single molecule. In order to be successful, the molecule must be physically flat and change state by altering the positions of hydrogen atoms without undergoing any structural modifications. Molecular memory uses chemicals that can change back and forth between two steady states, therefore it works much better when weighing against clusters of atoms that toggle magnetic states on the shell of hard drives. This type of data storage is far from being ready for commercial use since it needs more time and research.
