    摘要: A method to encode information holographically, wherein the method provides information, and generates a plurality of data images, wherein each data image comprises a portion of the information. The method holographically encodes each of the plurality of data images in a holographic data storage medium, generates a plurality of identifiers, and associates a different one of the plurality of identifiers with a different one of the plurality of data images. The method forms a directory image reciting each of plurality of identifiers, encodes the directory image in a non-holographic data storage medium, and holographically encodes the directory image in the holographic data storage medium.

    摘要: An apparatus and method are disclosed to generate convolution encoded data. The method supplies a convolution encoder. The method receives original data and generates convolution encoded original data. The method receives revised data. The method generates an XOR data stream by Exclusive OR'ing the original data with the revised data, forms a convolution encoded XOR data stream using the convolution encoder, and Exclusive ORs the convolution encoded XOR data stream with the convolution encoded original data to generate convolution-encoded revised data.

    摘要: A method is disclosed to encode information in a holographic data storage medium. The method supplies a holographic information storage system comprising a laser light source, a spatial light modulator, and a holographic data storage medium. The method energizes the laser light source using first power comprising a first current, disposes a data image on the spatial light modulator, and further energizes the laser light source using second power comprising a second current, wherein the second current is greater than the first current. The method forms a data beam comprising said data image, forms a hologram comprising said data image, and encodes an interference pattern comprising the hologram in the holographic data storage medium.

    摘要: A method for accessing data in a data storage system is presented. The method includes supplying a host computer that is in communication with the data storage system, where the data storage system includes a data storage medium and a holographic data storage medium. A first request is generated to access a directory encoded in the data storage medium and includes a first encryption key. The requested directory recites a listing of data files encoded in the holographic storage medium. If the first encryption key decrypts the directory, the directory is read and a data file encoded in the holographic data storage medium is identified. A second request is then generated to access the data file and includes a second encryption key. Finally, if the second encryption key decrypts the data file, then it is read.
