Abstract: PROBLEM TO BE SOLVED: To correct the wrong correction by correcting the bit shift of binary data which are read out of media and also generating the information on an uncorrected bit and its correcting direction. SOLUTION: A data reproducer is provided with circuits 24, 26 and 28 which correct the times of cross points between the read and slice signals and a circuit 20 which produces a gray bit that shows a time cell including an uncorrected cross point and another time cell adjacent to the correcting direction of the uncorrected cross point.
