摘要： The storage medium 30 for an optical data storage system is a contiguous laminate formed by a plurality of layers 18, 19, 20 of photochemical hole burning material, such layers individually exhibiting inhomogenous absorption spectrum characteristics spanning different, successive wavelength ranges. This arrangement greatly expands the cumulative or overall absorption band of the storage medium available for laser hole burning to implement data bit writing, and thus increases the storage density at each memory site. The absorption spectrum characteristics of the layers can be varied by including coloring dyes in the layers.
摘要翻译： 用于光学数据存储系统的存储介质30是由光化学空穴燃烧材料的多个层18,19,20形成的连续层压体，这些层分别呈现不同连续波长范围的不均匀吸收光谱特性。 这种布置大大地扩大了可用于激光孔燃烧的存储介质的累积或总体吸收带，以实现数据位写入，从而增加了每个存储器位置的存储密度。 层的吸收光谱特性可以通过在层中包括着色染料来改变。

摘要： An optical information recording and reproduction system uses an objective lens (5) to focus a light beam onto the information-carrying medium (6). To ensure the beam is focused correctly part of the reflected beam is transmitted to an optical component (10) which has a reflecting surface (11) with reflectivity or transmissivity which varies continuously with respect to the angle of incidence. A photo-detector (9) senses the distribution of intensity of the beam reflected by the surface (11).
