METHOD, CONTROLLER, COMPUTER PROGRAM AND DATA STORAGE SYSTEM FOR STORING, ACQUIRING, AND SEARCHING INFORMATION

摘要

PROBLEM TO BE SOLVED: To provide a device and method for storing, acquiring and searching information. SOLUTION: The method encodes information comprising a plurality of datasets in a holographic data storage medium to form an encoded holographic data storage medium, and encodes the same information to one or more of a plurality of non-holographic data storage media. The method then selects a dataset comprising a portion of the information, where the dataset is written to a dataset storage address on the non-holographic data storage medium, and illuminates the encoded holographic data storage medium with a dataset beam comprising the dataset to produce a dataset reference beam, such that the dataset reference beam strikes the optical detector at one or more dataset reference beam coordinates. The method then associates the dataset with the one or more dataset reference beam coordinates and with the dataset storage address. COPYRIGHT: (C)2008,JPO&INPIT
