    摘要： A method of making a holographic data storage medium is provided. The method comprises: (a) providing an optically transparent substrate comprising at least one photochemically active dye; and (b) irradiating the optically transparent substrate at least one wavelength at which the optically transparent substrate has an absorbance in a range from about 0.1 to 1, to produce a modified optically transparent substrate comprising at least one optically readable datum and at least one photo-product of the photochemically active dye. The at least one wavelength is in a range from about 300 nanometers to about 800 nanometers. The optically transparent substrate is at least 100 micrometers thick, and comprises the photochemically active dye in an amount corresponding to from about 0.1 to about 10 weight percent based on a total weight of the optically transparent substrate.

    摘要： 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.

    摘要： A thermoplastic composition is described, based on a copolycarbonate which includes at least two structural units. Structure I is usually a conventional carbonate based on bisphenol A, while structure II is a bisphenol carbonate which includes branched or linear groups extending from a bridging carbon atom or carbon group which connects two aromatic rings. The compositions exhibit very good melt flow, along with enhanced shear-thinning behavior. These characteristics are important for optical disc applications. Thus, related articles are described, along with processes for preparing such articles.
