Abstract

PURPOSE: To surely detect a detecting means moving to a next track by an easy method by comparing the number of an information track which is reproduced last time with the number of an information track which is reproduced this time and detecting the playback signal of the information track when those numbers are different from each other.
CONSTITUTION: This device is provided with a means 101 which detects error information on the track numbers of the last reproduced information track and information track reproduced this time and a means 127 which compares the track number of the information track reproduced last time with the track number of the information track reproduced this time. Then when there is no track number error, it is judged that the track numbers of both information tracks match with each other and when not, the track is regarded as a new track and information is detected, thus discriminating and reproducing information tracks. Consequently, a playback error is prevented from being caused by a track number error.
