Abstract

PURPOSE:To prevent an inversion phenomenon from being generated without impairing the definition of an image at the time of reproduction by shortening the time width of a spike at the time of recording, by setting the large frequency shift of a carrier and setting the small time constant of a pre-emphasis circuit in a wide band area mode. CONSTITUTION:Switches S-S are interlocked mutually, and they are switched to N sides at the time of ordinary mode recording, and to W sides at the time of wide band area mode. And a ratio of the frequency shift to a carrier frequency of an FM signal is set at a large level in the wide band are mode, and also the time constant of a main pre-emphasis circuit 12 at a small level in the wide band area mode. Thereby, the spike in the output of the main pre-emphasis circuit 12 falls comparatively steeply. In such a way, it is possible to prevent the inversion phenomenon from being generated due to the spike without impairing the definition of the image at the time of reproduction.
