Paper Abstract

The recording density limit of the collinear holographic memory purely determined by the optical system, that is under the assumption that the recording material is ideal, is estimated. Signal to noise ratio is decreasing with the increase of the number of overlapped hologram pages because of the increase of the off- and degenerated-Bragg diffraction from the gratings in the holograms increases. The signal to noise ratio is calculated with the plane wave model accompanied with statistical considerations. It is shown that 5 Tbyte recording in a compact disc size is possible in ideal case.
