A tracking control arrangement for a magnetic recording and reproducing device, comprises a magnetic tape, drive means for driving the tape, and at least two reproducing magnetic heads (1A, 1B) for simultaneously scanning different slant tracks (TRa, TRb) recorded on the tape. The magnetic heads (1A, 1B) have different azimuth gaps (g1, g2) respectively. The tracking control system further comprises means for detecting a phase error between signals reproduced by the two magnetic heads (1A, 1B), and means for controlling the relative positions of the tracks (TRa, TRb) and respective magnetic heads (1A, 1B) relative to one another in dependence on the phase error. |
