ABSTRACT:
A track readjustment arrangement for a video magnetic tape recorder in which at least two magnetic heads travel across the direction of motion of the magnetic tape, for the purpose of scanning signals that are recorded on the tape. The magnetic heads are carried on a rotatable head wheel, and they have air gaps with an azimuth angle that alternates mirror-inverted around the central axis of the wheel. The phase errors that may occur in the signals scanned by the magnetic heads are from the horizontal sync pulses. The magnetic heads provide individually control parameters that are derived from the magnitude and direction of the phase errors. The head wheel is axially varied and reset as a function of the control parameters.
