Chemistry May Provide a Digital Storage Solution.

Caption

CWRU chemists developed a space-saving method to store digital data optically, using four-symbol, or quaternary code. The four symbols are the absence of color and three colors -- fluorescent green, ultramarine and cyan -- produced when dyes contained in a common polymer are exposed to heat, ultraviolet light or both.
