Abstract
A data input method is applied to a holographic digital data storage system in which sequential binary input data bits are arranged in an interleaved manner among pages. A first data bit is arranged in a specific position of a predetermined page, a second data bit is arranged in a specific position having similar beam intensity with that of the first data bit. Using this method, the holographic digital data storage system can be less affected by the adverse effect of spatial beam intensity variations and makes the entire data interleaved automatically to obtain more stable output data.
Claims8
A method for arranging input binary data bits among a plurality of pages to be stored in a holographic storage medium, each page including M×N storage positions, one data bit being arranged at one storage position, wherein an X number of sequential binary data bits are arranged among successive Q pages and at least one data bit is arranged in each of Q pages, M, N, X, Q being positive integer greater than 1 and X being greater than Q.
