を特徴とするトラツキング制御装置。 A magnetic recording/reproducing device that records signals on multiple tracks using a plurality of recording heads arranged in the width direction of a running magnetic tape, and reproduces the recorded signals using a plurality of playback heads also arranged in the width direction of the tape. This tracking control device includes a head moving means for moving a plurality of playback heads in the width direction of the tape, and a pair of heads for detecting tracking deviation with respect to a predetermined recording track, which are spaced apart by the width of the recording track. two pairs of heads, switching means which usually take output from one pair of heads, and if no output is available from these, take output from the other pair of heads instead; The apparatus comprises a comparison means for comparing the outputs of a pair of heads and a means for creating a tracking control signal based on the output of the comparison means, and the head moving means is driven based on the tracking control signal. A tracking control device featuring:
