Disco took the groove-heavy Funk sound and emphasized the groove even more. Whereas Funk could be slow or fast and album or concept oriented, this stuff is all roughly the same bpm and is meant for the dancefloor. Disco got huge in the late ‘70s and crossed over into Pop and even Rock. Bigtime disco names are KC and the Sunshine Band, Donna Summer, and the Village People, but everyone from the Stones to Rod Stewart tried their hand at it.
