Abstract

Abstract An input section (11) inputs a recording signal to be recorded on a recording medium (T). An identifica­tion signal generator (14) generates a predetermined identification signal. A processor (13) is connected to the input section (11) and the identification signal generator (14), and selectively processes the recording signal and the identification signal. A detector (12) is connected to the input section (11), the identifica­tion signal generator (14), and the processor (13), and detects a recording restriction signal from the record­ing signal so as to control the processor (13) in accor­dance with a detection result. A recording section (REC) receives an output signal from the processor (13), and records the signal on the recording medium (T).
