Abstract
An information reproducing apparatus for reproducing digital information recorded in a recording medium. The apparatus includes a first binarizing unit for binarizing a reproduction signal read out of the recording medium, a differentiating unit for differentiating the reproduction signal read out of the recording medium, a second binarizing unit for binarizing a signal obtained by differentiating the reproduction signal in the differentiating unit, and a determining unit for determining the digital information in units of multiple bits, based on output signals from the first and second binarizing units.
