摘要:
An information recording disc has a control signal such as an address signal pre-recorded on a guide track which is pre-formed on the information recording disc at a position different from a track position where an information signal is to be recorded. An information signal recording apparatus for recording the information signal on such an information recording disc controls a rotation frequency of the information recording disc to a constant rotation frequency by locking a horizontal synchronizing signal within a composite video signal to edges of pulses reproduced from the guide track, and the information signal is recorded on the information recording disc so that a recording interval of the control signal is positioned within a vertical blanking period of the information signal at least including the composite video signal.
