Abstract
In a digital video tape recorder designed for recording each unit of video data in a plurality of tracks simultaneously by the use of a plurality of magnetic heads, the shift value between a track scanned by a magnetic head in a reproducing mode and another track recorded previously by the same magnetic head is decided from the majority of shift values obtained with respect to the individual magnetic heads, and the contents of identifying signals included in the pickup data are determined in accordance with the majority-decided shift value, whereby accurate shift values and identifying signals are ensured to consequently realize satisfactory picture reproduction.
