Abstract:
Memory elements that can handle more than just 1's and 0's could make for denser data storage. Now they can be made from multilayered, nanoscale plastic beads. Most materials for data storage, such as magnetic or optical disks, are capable of holding just a single bit of information at each site in the memory. But researchers in Canada have made a nanostructured plastic in which several different optical bits can be superimposed without interfering with each other.
