Abstract
A magnetic recording and/or reproducing apparatus and methods thereof for a composite color TV (television) signal arranged such that a luminance signal and a high band component of a chrominance subcarrier signal of the composite color TV signal are frequency modulated, recorded and reproduced, while a low band component of the chrominance subcarrier signal is frequency down converted to a frequency at a band lower than that of the frequency modulated signal, thus improving resolution of the color signal component.
