APPARATUS AND METHOD TO STORE, RETRIEVE, AND SEARCH BOTH ANALOG AND DIGITAL DATA

A method is disclosed to store, retrieve, and search both analog data and digital data. The method encodes information comprising a plurality of analog datasets in a holographic data storage medium to form an encoded holographic data storage medium, and further encodes digital data abstracted from the plurality of analog datasets to one or more of a plurality of non-holographic data storage media. The method then selects an analog dataset, wherein digital data abstracted from that analog dataset is written to a digital storage address on the one or more non-holographic data storage media, and illuminates the encoded holographic data storage medium with an analog dataset beam comprising the analog dataset. The encoded holographic data storage medium emits a dataset reference beam that strikes the second optical detector at one or more dataset reference beam coordinates. The method then associates the analog dataset with the dataset reference beam coordinate and with the digital storage address.
