Claims

[Scope of utility model registration request]

The information signal consists of at least a synchronization signal and address data, and each bit information of the address signal, which has a certain number of bits to indicate the position of the playback information of the playback element that picks up and plays back the recorded information signal, is distributed at a certain period and sequentially becomes the information signal. In an apparatus for reproducing a green signal recorded on a rotating recording medium, the synchronizing signal detecting circuit detects the synchronizing signal in the address signal that is discriminately separated from the reproduced signal; a storage circuit that temporarily stores the address data of N bits (N is a constant) in the address signal, and a reproduction mode signal during reproduction in which reproduction is performed while moving the reproduction element at a faster speed than during normal reproduction; and means for extracting only n bits (where n is a constant and n<N) of the storage address data of the storage circuit that are essential for detecting the position of the reproduction information by using the output detection signal of the synchronization signal detection circuit. Address data capture device in the device.
