Abstract
A method for storing data including: providing a first substrate having a plurality of micro-holograms therein, the micro-holograms being indicative of the data; providing a second hologram-supporting substrate; illuminating the plurality of micro-holograms in the first substrate through the second substrate, thereby producing a holographic pattern in the second substrate indicative of reflections of the plurality of micro-holograms in the first substrate; providing a third hologram-supporting substrate; and, illuminating the holographic pattern in the second substrate through the third substrate, thereby substantially replicating the plurality of micro-holograms in the first substrate in the third substrate.
