ABSTRACT:
An optical disc recording apparatus comprises a multiplexing circuit for frequency-division-multiplexing an FM luminance signal and the frequency converted carrier chrominance signal with a variable frequency-division-multiplexing ratio so that a frequency-division-multiplexing ratio of the frequency converted carrier chrominance signal with respect to the FM luminance signal becomes greater approximately proportionally to a relative linear velocity between an optical disc which rotates at the constant angular velocity and a laser beam which scans the optical disc, a limiter for converting an output frequency division multiplexed signal of the multiplexing circuit into a square wave having a constant amplitude, an amplitude varying circuit for varying an amplitude of the output square wave of the limiter approximately proportionally to the relative linear velocity, and a recording circuit including a laser light source for generating the laser beam responsive to an output signal of the amplitude varying circuit.
