INFORMATION REPRODUCTION DEVICE AND INFORMATION REPRODUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a method for eliminating an influence of crosstalk from a reproduction signal by generating a crosstalk component in a pseudo manner, taking into consideration of frequency and/or phase shift between an adjacent track and a reproduction track.

SOLUTION: An information reproduction device has: a delaying part for outputting a reproduction signal of an N-th track in reproduction of an (N+1(N: a natural number equal to or more than 2))-th track; a first waveform generating part for generating a crosstalk component of the (N+1)-th track on the basis of a first interference amount being a crosstalk amount from the (N+1)-th track to the N-th track and a first error amount being a shift between the (N+1)-th track and the N-th track; a second waveform generating part for generating a crosstalk component of an (N-1)-th track on the basis of a second interference mount being a crosstalk amount from the (N-1)-th track to the N-th track and a second error amount being a shift between the (N-1)-th track and the N-th track; and a waveform operating part for subtracting an output of the first waveform generating part and an output of the second waveform generating part from an output of the delaying part.
