ABSTRACT An apparatus for reading a record carrier on which a combined video signal is recorded in a single track, in particular a disc-shaped record carrier on which the signal is recorded in optically coded form. In order to reduce the disturbing effect of dropouts on the eventually obtained sound signal, the video signal is subjected to the action of a clamping circuit. Said clamping circuit normally transfers the applied video signal unmodified. During a dropout the video signal is clamped at its average value by means of said clamping circuit, so that a substantial improvement is obtained in respect of the sound signal.
