Abstract
An information reproduction apparatus is provided with a reproduction signal processing system for reproducing digital information recorded on an information track of a recording medium by a pit edge recording method and for reproducing the digital information by converting a reproduction signal read out from the recording medium into a binary signal after the reproduction signal is subjected to AC-coupling. The information reproduction apparatus is further provided with a phase compensation circuit arranged in the reproduction signal processing system to compensate for a phase distortion of the reproduction signal under the influence of the AC coupling.
