ABSTRACT:
This invention is directed to the storing of digital information. This storage system comprises a number of layers of transparent or translucent material. In each layer there is a chemical or chemicals subject to change by being contacted with different electromagnetic wave lengths. For example, if there be eight layers then the chemical or chemicals in any layer is subject to be changed by an electromagnetic radiation of a wave length different than for any of the other seven layers. In this manner, with eight layers it is possible to have an eight bit byte. Actually, under premutations and combinations it is possible to have as many as eight bit bytes from the eight layers. It is conceivable that there may be more than eight layers such as sixteen layers of thirty-two layers. There is the possibility of storing large amounts of information in a small volume.
