    摘要: An apparatus and method are disclosed to encode binary data into trinary data. Applicants' method provides binary data, and encodes that binary data into trinary data. By “binary data,” Applicants mean a plurality of bits, wherein each of those bits comprises a value selected from the group consisting of a first value and a second value. By “trinary data,” Applicants mean a plurality of bits, wherein each of those bits comprises a value selected from the group consisting of a first value, a second value, and a third value. The trinary data may be stored in ROM optical disks, nano-sized indentations in a thin-film, or multi-level magnetic storage. The trinary data may be also transmitted via three light levels in an optical communications network.

    摘要: An apparatus and method are disclosed to receive information and to generate, store, and read, a plurality of error correction coded data sets using that information. Applicants' storage controller receives information and generates (N) sets of error correction coded data, wherein (N) is greater than or equal to 2. The method writes, for each value of (i), the (i)th set of error correction coded data to the (i)th data storage medium, wherein (i) is greater than or equal to 1 and less than or equal to (N). If Applicants' storage controller receives a request to read the information, then Applicants' method reads each of the (N) error correction coded data sets, generates the information using the (N) error correction coded data sets, and returns the information to the requestor.

    摘要: A method to deduplicate data by receiving a data set, setting a data chunk size, selecting a first stage deduplication algorithm, and selecting a second stage deduplication algorithm, where the first stage deduplication algorithm differs from the second stage deduplication algorithm. The method selects a data chunk, where that data chunk comprises all or a portion of the data set, performs a first stage deduplication analysis of the data chunk using the first stage deduplication algorithm. If the first stage deduplication analysis indicates duplicate data, then the method performs a second state deduplication analysis of said data chunk using the second stage deduplication algorithm to verify the data as duplicate. Only if both data deduplication analysis indicate duplicate data the data chunk is replaced by a deduplication stub or reference to the identical data chunk which is already stored.

    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.

    摘要: A method is disclosed to optimize the performance of a holographic data storage system, where that holographic data storage system comprises a plurality of calibratable components, and where each of the plurality of calibratable components comprises one or operational parameters, and where each of those operational parameter is associated with a nominal range. The method seriatim tests each calibratable component and measures the one or more operational parameters for that device. The method determines if the one or more operational parameters associated with each of the calibratable components fall within the associated nominal ranges. If an operational parameter associated with a selected calibratable component fall outside the associated nominal range, then the method recalibrates that selected calibratable component.

    摘要: Data that is to be deduplicated and compressed is received. The data is compressed then deduplicated to generate first compressed then deduplicated data. The data is deduplicated then compressed to generate first deduplicated then compressed data. The first compressed then deduplicated data is stored if the first compressed then deduplicated data is smaller in size than the first deduplicated then compressed data. The first deduplicated then compressed data is stored if the first deduplicated then compressed data is smaller in size than the first compressed then deduplicated data.
