Abstract

An information signal recording disc comprises a first recorded region in which an information signal at least including a video signal is recorded, and a second recorded region in which an end signal is intermittently recorded. The end signal is used to forcibly and automatically return a reproducing element of a disc reproducing apparatus from a playing position to a rest position. The second recorded region is provided at a position prior to the first recorded region in a direction of a reproducing sequence of the recorded signals on the information signal recording disc. The disc reproducing apparatus comprises a detecting circuit for detecting the reproduced end signal, and a controller. The controller controls the detecting circuit so that the detecting circuit is made substantially inoperative in a state where the disc reproducing apparatus is coupled to an external device having a discriminating function.
