Title:
ホログラフィックデータ記憶方法及びそれから導かれるデータ記憶寿命の向上した物品
Document Type and Number:
Japanese Patent JP2009527796
Kind Code:
A
Abstract:
The present invention provides a method for storing holographic data comprising providing an optically transparent substrate comprising a photochemically active dye; 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, 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; activating the optically transparent substrate to form an intramolecular hydrogen bond to a nitrone oxygen in residual photochemically active dye, to stabilize the optically readable datum.
