Abstract
A three-dimensional optical memory system is disclosed which utilizes at least two layers of electron trapping media having different sensitivities to visible light coated on a substrate to store data in the form of light energy. Data is written onto the substrate, which may be in the form of a disk, which is contained in a light-tight contamination-free environment similar to a Winchester hard disk drive system, using at least two visible light laser beams having different wavelengths. Data is read from the disk using an infrared light laser beam. The at least two different data streams are separately detected. The system may be used as part of an optical disk drive system which is designed to fit within a standard mini or 51/4 inch disk drive form factor for personal computers.
