    "abstract": "We propose an optical read-out scheme allowing a demonstration of principle\nof information extraction below the diffraction limit. This technique, which\ncould lead to improvement in data read-out density onto optical discs, is\nindependent from the wavelength and numerical aperture of the reading\napparatus, and involves a multi-pixel array detector. Furthermore, we show how\nto use non classical light in order to perform bit discrimination beyond the\nquantum noise limit.",
