摘要： A hologram record apparatus (100) includes a spatial light modulator (15) and a control device (18). The spatial light modulator (15) is arranged on an optical path of signal light (L1) and divided into a plurality of cell blocks (151) arranged in a matrix. Each of the cell blocks (151) is further divided into a plurality of cells (152) arranged in a matrix. The spatial light modulator (15) can perform modulation on the cell basis. The control device (18) controls the spatial light modulator so as to modulate the signal light according to a plurality of record information sets to be recorded on a hologram record medium (200). Pluralities of modulation units (153) existing in the same cell block are not made into identical patterns. Since a plurality of cell blocks having a large pitch as compared to the pixel pitch are simultaneously or successively turned on/off, it is possible to reduce the distance between the zeroth-order light and the higher-order light.
摘要翻译：全息记录装置（100）包括空间光调制器（15）和控制装置（18）。空间光调制器（15）被布置在信号光（L 1）的光路上，并被分成以矩阵排列的多个单元块（151）。每个单元块（151）进一步被划分成矩阵排列的多个单元（152）。空间光调制器（15）可以基于单元进行调制。控制装置（18）控制空间光调制器，以便根据要记录在全息记录介质（200）上的多个记录信息集来调制信号光。存在于相同单元块中的多个调制单元（153）不被制成相同的模式。由于与像素间距相比具有大间距的多个单元块同时或连续地导通/截止，所以可以减少零级光和高阶光之间的距离。

摘要： A compatible hologram system has a supporting part for loadably supporting a recording medium made of a photosensitive material, a signal generating part for allowing a coherent beam modulated in response to predetermined data to enter the recording medium and providing a three-dimensional light interference pattern therewithin to produce a diffraction grating, and a data processing part for detecting reproduced data by diffracted light from the diffraction grating and demodulating the data to the predetermined data. The recording medium has a reference data area in which a reference diffraction grating corresponding to a three-dimensional light interference pattern of a coherent light beam modulated in response to reference data has been stored in advance, a sector data area in which sector data is recorded, and a user data area in which user data is recorded. The hologram system corrects the reproduced data in response to the reference data reproduced from the reference diffraction grating stored in the reference data area, the sector data reproduced from the sector area, and reference data provided within a reference memory of the data processing part, and demodulates the data to the predetermined data.

The parameter set device (19) modifies parameters for multiple recordings such as a record angle and a focal depth in relation to at least one of signal light (L3) and reference light (L2) and can fix the parameters. The move device (20) relatively moves the focus position of the signal light and the reference light in the direction along the record surface of a hologram record medium. The control device (18) performs control so that the parameter for the last recording used for recording at the m-th focus position is used as the parameter for the first recording at the m+1-th focus position.
