FIELD: information technologies.
SUBSTANCE: medium is represented by a set of wave guides, comprising central wave guide layers with a photosensitive medium, and solid input diffraction gratings with different periods, placed between the central wave guide layer with a photosensitive medium and a border wave guide layer of each wave guide along the entire surface. Reading is carried out by means of input of reading laser radiation directed at the multi-layer carrier at angle different for each wave guide into central wave guide layers with a photosensitive medium via solid diffraction input gratings.
EFFECT: higher validity in selective reading of optical information recorded in a multi-layer photosensitive medium.
