Abstract
A method for controlling tracking position during low-speed reproducing in a video cassette recorder (VCR) which provides noise suppression noise and increased image quality. In one aspect, in a VCR having a pair of main heads for reproducing video signals from a recording medium at a normal operating speed associated with said VCR, a method for controlling tracking position when reproducing at speeds lower than the normal speed comprises the steps of: detecting a period of an envelope waveform of a video signal which is reproduced by the pair of main heads; generating a pseudo head switching pulse (PHSP) signal in accordance with the detected period; and tracing a tracking position at a position where a voltage level of the envelope waveform is the largest within one period of the PHSP signal.
