Abstract
The present invention provides a method for storing holographic data comprising providing a holographic storage medium comprising an optically transparent substrate including a photochemically active dye having at least two nitrone groups; and irradiating the optically transparent substrate with a holographic interference pattern, wherein the pattern has a first wavelength and an intensity both sufficient to convert, within a volume element of the substrate, at least some of the photochemically active dye into a photo-product, and producing within the irradiated volume element concentration variations of the photo-product corresponding to the holographic interference pattern, thereby producing a first optically readable datum corresponding to the volume element.
