A data reproducing device for generating a reproduced signal with an improved quality. The data reproducing device comprises a phase error detecting section (153) for determining the cross correlation between the head pattern on a track of a reproduction object and the reproduced signal, cross correlators (166, 167) for determining the cross correlation between the head pattern on a track adjacent to the track of the reproduction object and the reproduced signal, and a crosstalk detecting section (168) for determining the direction and ratio of the crosstalk from the cross correlations. Alternatively, the data reproducing device has a correction function of correcting the offset and gain of the reproduced signal according to the phase error and correlations determined by the phase error detecting section (153).
