Abstract
An information reproducing apparatus for reproducing digital record information recorded on an information record medium is provided with: a generating device for reading out the digital record information from the information record medium to thereby output a reproduction signal; a sampling device for sampling the reproduction signal by using a sampling clock signal having a predetermined sampling frequency to thereby output the sampled reproduction signal; a detection device for detecting a direct current level of the sampled reproduction signal by extracting a zero-cross sample value, which is a sample value contained in the sampled reproduction signal and is the closest sample value to a zero level in the sampled reproduction signal, from the sampled reproduction signal; a correcting device for correcting the sampled reproduction signal by subtracting the detected direct current level from each sample value of the sampled reproduction signal to thereby output the corrected sampled reproduction signal; and a reproducing device for decoding the corrected sampled reproduction signal to thereby reproduce the digital record information.
