ABSTRACT OF THE DISCLOSURE A video signal reproducing apparatus comprises a fixed head mounted on a rotary head drum, and a movable head supported on the head drum so as to lag the fixed head by a predetermined phase, and mounted on a bimorph plate so that the position of the movable head can be controlled transversely of a skew track on a magnetic tape. A delay circuit matches the phases of the signals reproduced by the fixed and movable heads, and in dependence on the levels of the reproduced signals the scanning path of the movable head is adjusted relative to the scanning path of the fixed head such that a reduction in one reproduced signal level causes an increase in the other reproduced signal level when the reproduced signals are phase-matched. The output is then complemented by at all times selecting the higher level reproduced signal with a selection switch.
