ABSTRACT:
A magnetic recording and reproducing apparatus which converts a video signal to an FM signal and records the FM signal on a magnetic recording medium has a filter which eliminates an upper sideband component of the FM signal before recording so as to thereby enhance an increase of the levels of the lower sideband components of the reproduced and thereby improve its S/N ratio FM signal.
