ABSTRACT:
A tracking device is disclosed. When a target track is indicated by indicating means, the head is shifted toward the target track. During this time, prior to the detecting the signal for a position of the target track, the signals for the adjacent positions to the position of the target track on either side are detected, and, after that, the signal for the position of the target track is detected. Based on the outputs of these positions, discriminating means determines the position to which the head is tracked relative to the recording medium.
