Abstract
An input section inputs a recording signal to be recorded on a recording medium. An identification signal generator generates a predetermined identification signal. A processor is connected to the input section and the identification signal generator, and selectively processes the recording signal and the identification signal. A detector is connected to the input section, the identification signal generator, and the processor, and detects the presence of a recording restriction signal from the recording signal so as to control the processor in accordance with a detection result. A recording section receives an output signal from the processor, and records the signal on the recording medium.
