摘要： PROBLEM TO BE SOLVED: To suppress a tilt error even when the tilt error is caused in a holographic memory in a direction perpendicular to a surface including optical axes of a signal beam and a reference beam (radial tilt direction).
SOLUTION: A reference tilt hologram for specifying a reference incident angle in the radial tilt direction is recorded in advance on a holographic memory medium. During recording and reproducing operations, the reference beam is emitted to a recording position of the reference tilt hologram and the reference incident angle (reference angle Sr) of the reference beam in the radial tilt direction is detected based on a received light state. A tilt actuator 19 for displacing the holographic memory medium in the radial tilt direction is driven to adjust an incident angle of the reference beam in the radial tilt direction to the reference angle Sr. Then, the signal beam and the reference beam are emitted to the holographic memory medium to execute the recording and reproducing operations.

摘要： PROBLEM TO BE SOLVED: To properly reproduce information from a holographic memory even when a tilt error occurs in a direction vertical to a surface including optical axes of signal light and reference light. SOLUTION: During reproduction, a holographic memory 10 is fed stepwise from an initial access position with respect to a reproduction target block within a fixed back and forth range in a disk circumferential direction. In each stepwise-fed position, an SNR of a reproduction signal is calculated by an SNR calculation circuit 19 to detect the quality of the reproduction signal. A disk circumferential direction position in which an SNR becomes best is set in a circumferential direction position with respect to the reproduction target block. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a hologram device capable of properly erasing a recording mark having a predetermined depth.SOLUTION: In a recording layer 12, a recording mark M by a hologram is formed. An optical pickup device comprises: a laser light source 101 for emitting a laser beam; a collimator lens 103; a lens actuator 104 for displacing the collimator lens 103 in an optical axis direction; and an objective lens 106 for converging the laser beam to the recording layer 12. When the recording mark M is erased, the collimator lens 103 is driven, and the laser beam is spread from a parallel light. Thereby, a focus position of the laser beam is displaced in a depth direction of the recording layer 12. Thereby, when the recording mark M is erased, the recording mark M is irradiated with the laser beam in a range wider than that when reproduced.

摘要： PROBLEM TO BE SOLVED: To smoothly eliminate stray light and crosstalk between layers by an inexpensive and simple configuration, while maintaining usage efficiency of reflected light. SOLUTION: Light detectors 111a and 111c are disposed at positions away from a collimating lens 110 in comparison with the convergent point Fp of reproducing light Ln. A light detector 111b is disposed at a position near the collimating lens 110 in comparison with the convergent point Fp of the reproducing light Ln. The light detector 111b receives the upper half of the reproducing light Ln. The light detector 111a receives the lower half of the reproducing light Ln. When the light detector 111b is removed, the upper half of the reproducing light Ln enters the light detector 111c. Provided that detection signals outputted from the light detectors 111a, 111b and 111c are referred to as Sa, Sb and Sc, respectively, a reproducing signal S is obtained by calculation of S=Sa+Sb-Sc, thereby completely eliminating influences of stray light from the reproducing signal S.

摘要： PROBLEM TO BE SOLVED: To provide an optical recording medium and optical recording device increasing the capacity with no limitation on the number of recording layers, and to provide an optical reproducing device suitably used for reproduction of the recording medium. SOLUTION: Frequency bands of recording signals in adjacent recording layers are made different from each other. When a target recording layer is reproduced, reflection light (signal light) from this recording layer and reflection light (stray light) from recording layers adjacent to this recording layer in a layered direction are simultaneously made incident in a photodetector 112. However, since a frequency band of a signal resulting from the stray light is different from that of a signal resulting from the signal light, the signal resulting from the stray light is cut off by a filtering circuit 210a or 210b. Thereby, a noise component resulting from the stray light is removed from the reproduction RF signal and smooth reproducing operation can be achieved. COPYRIGHT: (C)2009,JPO&INPIT
摘要翻译：要解决的问题：提供一种光记录介质和光记录装置，其增加容量而不限制记录层的数量，并且提供适合用于再现记录介质的光学再现装置。解决方案：使相邻记录层中的记录信号的频带彼此不同。当再现目标记录层时，同时将来自该记录层的反射光（信号光）和与层叠方向相邻的记录层的记录层的反射光（杂散光）入射到光电检测器112中。然而，由于由杂散光产生的信号的频带与由信号光产生的信号的频带不同，由杂散光产生的信号被滤波电路210a或210b截断。由此，从再现RF信号中除去由杂散光产生的噪声成分，可以实现平滑的再现动作。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an optical recording medium capable of attaining high capacity without limiting the number of recording layers, to provide an optical pickup apparatus suitably used for the recording medium and to provide an optical reproduction device. SOLUTION: Polarization rotation layers 13 are disposed between adjacent recording layers 12. The polarization rotation layer 13 rotates the polarization direction of laser light by 90°, for example, when the laser light goes and returns. Thereby, a polarization direction PH of the laser light reflected by an odd numbered recording layer from a laser light incident surface and a polarization direction PV of the laser light reflected by an even numbered recording layer are orthogonal to each other. Thus deterioration of signal quality due to stray light can be suppressed by extracting and introducing light of the polarization direction PH to an optical detector when the odd numbered recording layer is a target recording layer.

摘要： PROBLEM TO BE SOLVED: To provide a hologram memory device which can properly record a recording signal without fail even when pixel collapse occurs in a spatial light modulator or when dirt, dust, etc. attached to an optical system arranged in an optical path of object light. SOLUTION: The object light is incident on a spatial light modulator, while inputting an electrical signal (transmits a luminous flux) of "1" in each pixel of the spatial light modulator. The incident light all penetrate the spatial light modulator and the light is received by a CCD. At this time, if the pixel collapse arises in the spatial light modulator, an electrical signal in the electrical signals from the CCD and corresponding to the pixel collapse position becomes Low (= 0). By detecting this, the pixel collapse position of the spatial light modulator can be detected. The collapse position of a pixel of the spatial light modulator is nullified in the recording and instead, a pixel of a spare area is set for assignment of a recording signal. Information on a nullified pixel and an alternative pixel is recorded in a management area of the hologram memory. COPYRIGHT: (C)2006,JPO&NCIPI
