摘要：A reproducing device includes a detection circuit and an integration circuit. Thedetection circuit detects a push-pull signal PP. The integration circuit carries out

integration processing with respect to one or greater frames of the push-pull signal, andcarries out binarization processing with respect to integration results thus obtained,thereby detecting sub data. In the integration circuit, the more the frames to be used fordetecting sub data is, the higher the accuracy of the detected sub data is. The

reproducing device further includes a control circuit for controlling the total number ofthe frames to be used for generating valid sub data in the integration circuit. The controlcircuit controls the total number of the frames in accordance with a result of an errorcorrection made by an error correction circuit.
