    摘要: Provided are optical information processing apparatus and method. In the optical information processing apparatus and method, when the recording regions in which optical information is recorded in an angular multiplexing scheme overlap with each other, a recording angle and a recording position for optical information is adjusted so as to improve reproducing efficiency of readout beams reproduced from the overlap recording regions, so that heights of “null” for diffraction energy reproduced from the recording regions and overlap recording regions can be lowered. Accordingly, it is possible to reduce crosstalk noise during the recording and producing of the optical information and to improve optical information recording quality and reproducing efficiency

    摘要: In order to pick up a digital storage medium including a holographic storage medium and a reflective storage medium, a first and a second beam each of which has a different wavelength are used and a reflected beam and a reconstructed signal beam are propagated through a propagation path, wherein the first beam is reflected by the digital storage medium to generate the reflected beam and the second beam is diffracted by a holographic interference pattern in the holographic storage medium to generate the reconstructed signal beam. A polarizing beam splitter is used to split the reflected beam from the propagation path while a laser line mirror is used to separate the reconstructed signal beam from the propagation path.

    摘要: In a storing mode of an apparatus for storing and retrieving a sequence of digital page data, a first/second complex reference beam and a modulated signal beam converge on a storing location to generate a sequence of first/second interference patterns to be sequentially stored on a holographic medium. A shift selectivity of the first complex reference beam is larger than that of the second complex reference beam so that the second interference pattern is used as a servo pattern to sequentially determine where the first interference patterns have been stored.

    摘要: A method for mapping 2N message N-tuples into 2N+1 codeword (N+1)-tuples is developed. The 2N+1 codeword (N+1)-tuples are categorized into M subsets of codeword (N+1)-tuples, wherein M is an integer larger than 1, each subset G has NG codeword (N+1)-tuples and the total number of codeword (N+1)-tuples in the M subsets is 2N. Each subset G has a predetermined number KG of lower bits and a predetermined number (N+1−KG) of higher bits, and the number of lower bits in every codeword (N+1)-tuple in any subset is not equivalent to that of lower bits in every codeword (N+1)-tuple in any other subset. The 2N message N-tuples are matched with the 2N codeword (N+1)-tuples in the M subsets, respectively, in one-to-one correspondence to generate a lookup table.
