A method and an apparatus for recording and reproducing a TV broadcasting signal includes a CM detecting unit, a write data processing circuit, a recording system control circuit, and a recording medium. The CM detecting unit operates to detect if a TV broadcasting signal composed of a RF signal inputted through an antenna is now a CM. The write data processing circuit operates to generate CM information accompanied with the CM detected by the CM detecting unit. The recording system control circuit operates to record on the recording medium the CM information generated by the write data processing circuit together with a video signal and an audio signal.
