摘要： PROBLEM TO BE SOLVED: To achieve both increase in high recording density by diffusing spectrum of signal light on a hologram recording medium by a phase mask and increase in high recording density, by enabling reduction of a diameter of the signal light using an aperture by controlling interference among codes. SOLUTION: When reading of data is performed by irradiating a hologram recording medium with reference light during reproduction, coherent light of which the phase is the same as that of a reproduced image, obtained in accordance with irradiation of the reference light and of which the intensity is larger than the absolute value of the minimum value of amplitude of the reproduced image; whereas the square root is calculated for a read signal obtained by an image sensor, the DC component corresponding to the coherent light is excluded and reproduction of data is performed. By conducting reading of such three kinds of recording values +1, 0, -1 by the phase mask linearly by performing such a read-out operation, an equalizing filter for preventing interference between the codes can be operated effectively, and both increase in high density recording can be achieved.

摘要： PROBLEM TO BE SOLVED: To provide a hologram recording and reproducing apparatus capable of relaxing requirement on accuracy of alignment of a one-dimensional light receiving element and a one-dimensional optical modulation element, and also can reproduce a clock satisfactorily without using a preamble.
SOLUTION: The number of light receiving elements is made larger than the number of optical modulation elements and data are over-sampled. Zero cross timing of a read signal is extracted, a clock signal matching with the timing is obtained by frequency analysis. The read signal is sampled at the timing. Preamble and pixel matching becomes unnecessary. The requirement on accuracy of alignment of the one-dimensional light receiving element and the one-dimensional optical modulation element therefore can be relaxed, while the clock can be reproduced satisfactorily without using a preamble.

摘要： PROBLEM TO BE SOLVED: To provide a recording/reproducing method by which expansion of storage capacity to a hologram recording medium can be achieved. SOLUTION: The minimum bedding unit of data into a circular signal light area is miniaturized than before. Percentage of syncs to be inserted into recorded data for alignment during reproduction is also reduced. At this time, deterioration of alignment accuracy during reproduction is concerned due to decrease of sync percentage. Therefore during reproduction, sync detection is made to be performed using plurality of syncs of perimeter target sync. Thereby, even when there are few syncs, data reproduction can be performed properly. COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：要解决的问题：提供一种可以实现对全息图记录介质的存储容量的扩展的记录/再现方法。
解决方案：将数据转换为圆形信号灯区域的最小床单数量比以前小。在再现期间插入到记录数据中用于对准的同步的百分比也减少。此时，由于同步百分比的降低，重放期间对准精度的恶化。因此，在再现期间，使用周边目标同步的多个同步进行同步检测。由此，即使在几乎没有同步的情况下，也可以适当地进行数据再现。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To achieve robust reproduction in a hologram reproducing apparatus. SOLUTION: Two-dimensional FFT based on the output image of an image sensor is performed, and respective clock signals in an X direction and a Y direction included in the images are extracted from the analyzed result.

Since the resembling position can be specified using the whole including not only sync in the image but also user data, more robust reproduction is realized. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To expand the flexibility for manufacturing phase mask, and to readily manufacture a mask to be used in a system that employs a coaxial hologram recording and reproducing system.
