摘要： A method of recording holographic information includes recording a hologram mark and a homogeneous mark in a holographic data storage medium with a volume to alternatively locate the hologram mark and the homogeneous mark. The hologram mark has a varied refractive index distribution due to constructive/destructive interferences between two light beams and indicates information, while the homogeneous mark has a more uniform refractive index distribution than the hologram mark.
摘要翻译：记录全息信息的方法包括在具有体积的全息数据存储介质中记录全息标记和均匀标记，以交替地定位全息标记和均匀标记。由于两个光束之间的建构性/破坏性干扰，全息图标记具有不同的折射率分布，并且指示信息，而均匀标记具有比全息标记更均匀的折射率分布。
