ABSTRACT OF THE DISCLOSURE A video tape recorder for recording and reproducing a color video signal on a magnetic tape with different amounts of recording and reproducing time, includes a capstan drive assembly for advancing the magnetic tape; a recording section including A/D converters for converting the color video signal into digital form such that the digitized color video signal has a recording sampling frequency associated therewith, an encoder for encoding the digitized color video signal at a recording operating frequency, and rotary magnetic heads for recording the encoded signal on the magnetic tape; a reproducing section including rotary magnetic heads for reproducing the encoded signal from the magnetic tape, a decoder for decoding the reproduced encoded digitized color video signal at a reproducing operating frequency to produce a digitized color video signal having a reproducing sampling frequency associated therewith, and digital-to-analog converters for converting the digitized color video signal from the decoder into analog form; and a control device for controlling changes in the speed of rotation of the recording heads, the recording speed of the magnetic tape and the recording operating frequency of the encoder with the same ratio .alpha. such that the recording sampling frequency changes with the same ratio .alpha. and for controlling changes in the speed of rotation of the reproducing heads, the reproducing speed of the magnetic tape and the reproducing operating frequency of the decoder with the same ratio .beta. such that the reproducing sampling frequency changes with the same ratio .beta..
