Abstract
The beam intensity of an optical recording system employed for recording frequency modulated composite video signals on discs undergoes temporal distortion at critical signal frequencies in a manner complementary to the effects of frequency distortion in the spatial frequency response of the recording system. Concomitant recording of the composite signal and a groove effects a practical elimination of signal track drop which results when recording is effected on pre-grooves discs, and additionally eliminates frequency response distortions in the recorded signal due to the optical recording system.
