Paper Abstract

The multi-layered structure of the data storage is proposed for the holographic carrier recording density increase. The noises arousing from the diffraction of both the reconstructing beam and the reconstructed signals on the holograms of the neighboring layers are taken into consideration during the assessment of the resulting signal- to-noise ratio. It is concluded that with an appropriate diaphragm and layers geometry, as well as with sufficiently low holograms diffraction efficiency in layers, it is possible to increase the carrier information capacity in several times without essential deterioration of the read- out quality.
