Abstract

PURPOSE: To improve the quality of the reproduced picture at the normal reproduction time by obtaining the tracking control signal based on the tracking reference signal through a simple method and then giving the tracking control to the magnetic head via the tracking control signal.
CONSTITUTION: The carrier chrominance signal isolated from the color video signal receives the frequency conversion through frequency converter CONV1 and then recorded on recording medium T after changed into the low-range conversion carrier chrominance signal. In that case, the signal from subtractor SUB is applied to gate circuit G and inverter gate circuit IG to deliver the difference signal featuring the fixed phase in the constant and individual way. In addition, two signals of the opposite phase to each other of the signal from selection gate SOG3 are applied, and the signal featuring the specified phase difference is delivered to each output. This specified phase difference signal is applied to synchronous detector SD, and the tracking control signal is delivered via the sampling pulse sent from sampling pulse generation circuit SP. With this control signal, the tracking control is given to magnetic heads Ha and Hb to secure a high-quality reproduced picture.
