  • Adjustment Of The Magnetic Head Position Track Following On Tapes (AREA)

Abstract

PURPOSE: To dispense with control signal and control track, by performing tracking control with pilot signal recorded in the color signal in the vertical synchronizing signal period.
CONSTITUTION: Reproduced RF signal is divided into a luminance signal and a color signal by a circuit 8, and the color signal is high band transformed in a circuit 10 to be signal C. Gate circuits 54, 55 pick up pilot signals V1', V3', which are recorded in the signal C, and said polot signals are rectified by diodes D1, D2 to be signals (f), (g). These signals are supplied to clamp circuits 57, 58, and passed through filters 59, 60 to be direct-current voltages corresponding to the amplitudes of reproduction pilot signals. Then, these voltages enter a comparator circuit 61 and become high or low voltage, based on the voltage when the amplitudes of signals V1' and V3' are equal to ech other. Therefore, by constituting the error voltage of circuit 61 so that the rotating speed of capstan motor be higher when V1'>V3' and lower when V1'<V3', the head can be stably scanned on the recording track without using control signals or the like.
