摘要: The invention relates to a holographic data memory (1) comprising polymer film embodied in the form of layer (2). refractive index can be changed locally by means heat. Said is designed store optical phase information related local path length which transilluminated when being read out. An absorber dye (8) assigned order at least partially absorb writing beam used input information, and release heat thus produced A reflecting (6) preferably arranged behind
