A composite record/playback device capable of independently using recording media of different forms, i.e. a video tape record/playback block and a hard disc drive block, comprises a video tape record/playback unit, a hard disc drive, a first encoder, a first decoder and a second decoder for receiving and expanding a playback signal of the hard disc drive. By providing a first decoder and a second decoder, the signals played back by the video tape record/playback unit and the hard disc drive can be independently expanded by the first decoder and the second decoder. This allows an AB roll editing by the playback of the video tape record/playback unit and the hard disc drive.
