A new way of information storage using red, green, blue and black color imprints

Technical Paper


Herein we report the development of a new way of information storage using a scheme based on four colors, namely red, green, blue and black. This provided the advantage of not only storing information in four-color bits, but also in terms of transition from one color to another also representing information storage. The practical demonstration of the method was achieved using a photolithographic principle with colored films as the medium of storage. A CCD camera fitted to an optical microscope was used to retrieve the stored information. The present method provides not only an alternative but also the possibility of higher information storage capacity in comparison to compact disc, digital versatile disc and blu-ray disc technology.
