路。[Claims for Utility Model Registration] One frame worth of F for a disc on which an FM address signal including a horizontal synchronization signal is pre-recorded in the radial direction of the disc.
In an image file in which an M video signal is formed as concentric tracks, an address signal detection circuit detects an FM address signal from the playback output of the pickup, and a carrier oscillation circuit derives a carrier component of a frequency corresponding to the pedestal level of the FM video signal. A video file address signal circuit comprising: a switching circuit for deriving a carrier component in place of the playback output of the pickup based on the address signal detection output; and an FM demodulation circuit for FM demodulating the switching output.
