Abstract:
An information detecting apparatus which processes an analog signal corresponding to codes of a partial response format in synchronism with a given clock signal and outputs level information and/or phase information corresponding to a level and/or a phase of the analog signal, comprising:first prediction value calculating means for calculating a prediction value of a code of a partial response format that constitutes a predetermined, given pattern in accordance with a past prediction value of the code; andinformation calculating means for calculating the level information and/or the phase information from a value of the analog signal and the calculated prediction value of the code,wherein,the pattern is such that a pattern {0, 1, 0, -1 } consecutively appears a given number of times, andthe first prediction value calculating means calculates a prediction value of a code of a partial response format that constitutes the pattern in accordance with a 1-clock preceding prediction value of the code.
