Information reproducing method and apparatus for reproducing digital information by determining the information in multiple bit units based on binarizer output signals

摘要

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.
