Abstract

PURPOSE: To make it possible to record both stereo signals on a recording medium with high density and high quality by PCM-modulating stereo signals through three- position modulation and then by mixing them with FM-ed color video signals.
CONSTITUTION: Color video signals are delayed 2 by as long as a fixed value and then supplied to FM modulator 3. Further, digitized stereo sound signals are PCM- modulated through three-position modulator 6, band-limited by square-law cosine filter 7, and supplied to attenuator 8. Then, FM-modulated color video signals and 3PM-type PCM-modulated sound signals are mixed 4 and supplied to cutting machine 10 through hard limiter 9. Further, a line of bits varying length or interval in a scan direction corresponding to signals is formed on a mask disk recording medium to form a spiral recording track.
