ABSTRACT OF THE DISCLOSURE In an apparatus and method for optically recording on an optical disk a TV signal comprised of a color image signal and an audio signal; one horizontal period portion of an original luminance signal and one horizontal period portion of two original color difference signals from a standard TV signal are time-base-compressed to generate a time-base-compressed video signal for one horizontal period, the audio signal is digitized and time-base-compressed, and then the time-base-compressed digital audio signal and the time-base-compressed video signal are time-division- multiplexed with each other and recorded on the optical disk. BACKGROUND OF THE INVENTION Field of the Invention The present invention relates generally to an apparatus and a method for optically recording color image and audio signals, and more particularly is directed to an apparatus and method of this kind which are applicable to a so-called optical Write-Once system. Description of the Prior Art It has been proposed to record a color image signal and an audio signal on an optical disk with the frequency spectra shown in Figs. 1A and 1B, respectively.
