According to the present invention, there is provided an information recording apparatus in which, even when it cannot previously determine that a recording signal with any attribute is inputted, recording information conformable to DVD video standards etc. which is recorded in an available optical disc can be prevented from being illegally copied with a simple and low-cost configuration. According to this, there is provided an information recording method including the processes of: detecting whether a recording signal to be inputted from the outside is a recording signal conformable to DVD video standards only for playback; detecting whether the recording signal includes an inhibition flag indicating that the recording signal is inhibited from being recorded as an analog signal; and, when it is detected that the recording signal conforms to the DVD video standards and that the recording signal includes the inhibition flag, inhibiting the signal from being recorded.
