Abstract:
1. A reproducing apparatus for reproducing data stored to a data storage medium, comprising: synchronization pattern detecting means for detecting a synchronization pattern from a reproduced signal of the storage medium data; error detecting means for detecting an error between an amplitude of the reproduced signal and a reference point, the reference point being specified by a time at which a half cycle has elapsed from a start time of one cycle of a clock signal reproduced from the reproduced signal; and correcting means for correcting a deviation of the data from the clock signal corresponding to the error between the amplitude of the reproduced signal and the reference point, the deviation of the data being corrected on the basis of a difference between an interval of the synchronization pattern detected and a predetermined period, and on the basis of a segment time based upon the error detected, the segment time corresponding to a time at which the deviation of the data from the clock signal has occurred, the segment time being one of a plurality of segments into which the interval of the synchronization pattern is divided.
