Abstract

PURPOSE: To reproduce uniform good-quality pictures throughout all regions of a disc by controlling a band gain control circuit of reproducing signals according to reproducing positions in respect to reproducing of video signals of the optical video disc.
CONSTITUTION: The reproducing signal from disc 15 is converted to an electric signal by photo detectors 8a and 8b and is inputted to band gain control circuit 101 through adder 9. Meanwhile, the transfer quantity of disc 15 obtained by detection part 110 and the position of optical transfer material I (the part inside the one- dotted broken line) obtained by detection part 112 are converted to DC voltages by circuits 111 and 113 respectively and are added by adder 114 to obtain a DC voltage corresponding to the reproducing position of disc 15. Next, the gain of band gain control circuit 101 is so controlled by this DC voltage that the reproducing signal from disc 15 above may be larger for outside circumference reproducing of disc 15 than that for inside circumference reproducing, thereby compensating the reproducing signal.
