    摘要： The optical information recording and reproducing method realizes an increased number of multiplexing in recording and favorably stabilized signal recording in a manner of uniforming media consumption in angle-multiplexed recording by changing a phase of signal light on a pixel basis in a manner in which the speed of a phase change on a pixel basis is constant or is greater than or equal to a certain speed in a page and between pages when the driving speed of a phase mask changes at the time of recording. The optical information recording and reproducing method, while moving an optical element that adds phase information to a light flux which includes two-dimensional page data information in a direction that is perpendicular to an optical axis of the light flux, records the page data on the recording medium by adding the phase information to the light flux.

    摘要翻译： 光信息记录和再现方法通过以像素为基础改变信号光的相位，以通过以下方式改变角度多路复用记录中的媒体消耗的方式，实现了记录和有利地稳定的信号记录中的多路复用数量的增加：速度 基于像素的相位变化是恒定的，或者当记录时相位掩模的驱动速度改变时，在页面中和页面之间大于或等于一定速度。 光信息记录和再现方法在将包括二维页数据信息的光通量相加信息的光学元件移动到垂直于光通量的光轴的方向上时，将该页数据记录在 通过将相位信息添加到光通量来记录介质。

    摘要： An optical information recording and reproducing device that records information on a recording medium and/or reproduces information on the recording medium, using holography is configured to include a laser light source that performs irradiation with laser light, a first light-shielding portion which is capable of switching between transmission and shielding of laser light emitted from the laser light source, and a driving circuit that drives the switching between transmission and shielding of the first light-shielding portion, and a first movement portion that moves the first light-shielding portion.
