Reports that researchers in Italy and Scotland have developed a data storage device based on thin films of molecules called rotaxanes. Capability of holding up to 100 gigabits of information per square inch; Use of self-assembling molecules; Employment of the scanning atomic force microscope tip to stimulate the rotaxane molecules to make them reorganize themselves into nuclei, which grow to form dots.
