Abstract
For an off-axis holographic data storage system using a plane-wave reference beam and angular multiplexing recording, we define αlim to show the limit of material thickness shrinkage, which is compensable by shifting the read reference beam angle with a mount of Δθ to prevent the bright pixel intensity of the reconstructed image from becoming lower than a specific threshold Ith. In this work, we systematically analyzed the characteristics of αlim and corresponding Δθ for different recording parameters by the first Born approximation of the scalar diffraction theory.
