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.
本发明提供了一种存储全息数据的方法,包括提供一种全息存储介质,该介质包括一个光学透明基底,其中包含至少具有两个亚硝基团的光
化学活性
染料;并使用全息干涉图案照射光学透明基底,其中该图案具有第一波长和足够的强度,以将光
化学活性
染料在基底的体积元素内至少转化为一个光产物,并在照射的体积元素内产生与全息干涉图案相对应的光产物浓度变化,从而产生与该体积元素相对应的第一光学可读数据。
