Abstract
The invention relates to a data support () with a core layer () and at least one adjacent layer (), laminated to the core layer and a corresponding production method, said core layer being embodied from a holographic data store in the form of a volume hologram (). The surface () facing the core layer, on the layer directly adjacent to the core layer, has a roughness (), before lamination to the core layer, which affects the wavelength shift of the image reconstructed by the volume hologram.
