20090168627 | METHOD OF READING OPTICAL INFORMATION AND METHOD OF RECORDING OPTICAL INFORMATION - Provided are methods of recording and reading optical information in a recording medium using holography. In the method of recording optical information, a first recording operation is performed for recording optical information in a first recording region in an overlapping manner by allowing a reference beam and a signal beam with data loaded to interfere with each other in the first recording region, the reference beam being angularly multiplexed at predetermined intervals. Furthermore, a second recording operation is performed for recording optical information in a second recording region adjacent to the first recording region in an overlapping manner by allowing the reference beam and the signal beam to interfere with each other in the second recording region, the reference beam being angularly multiplexed between the predetermined intervals. Consequently, optical information can be recorded so as to easily detect and determine a selected reproducing beam, thus increasing the reading efficiency of the optical information. | 07-02-2009 |
20090168630 | METHOD FOR DETECTING PATTERN OF OVER-SAMPLING IMAGE AND AN OPTICAL INFORMATION PROCESSING APPARATUS AND METHOD USING THE SAME - Provided are a method for detecting a pattern of an over-sampling image and an optical information processing apparatus and method using the same. A method for detecting a pattern from an image of an over-sampled datapage includes: over-sampling the datapage to detect a detection image of the datapage; comparing the detection image and a reference image of over-sampling for the pattern by a covariance; and calculating a pixel of the pattern over-sampled by values of the reference image and the detection image compared by the covariance. Accordingly, data with a specific pattern such as a mark can be detected from an image of an over-sampled datapage, thereby making it possible to increase the data reproduction accuracy, thus making it possible to greatly increase the reliability of reproduced optical data. | 07-02-2009 |
20090172497 | DATA PROCESSING SYSTEM AND METHOD FOR PROCESSING OPTICAL INFORMATION - Provided is a data processing system for recording holographic optical information.
