Digital audio signal recording device for motion picture film and audio signal recording system for motion picture film employing the digital audio signal recording device

A digital audio signal recording device which, in conjunction with a film magazine loaded with a motion picture film and an analog audio recording device recording analog audio signals on the motion picture film, constitutes an audio signal recording system for the motion picture film capable of recording both analog audio signals and digital audio signals on the motion picture film delivered from the film magazine. The digital audio signal recording device transports the motion picture film, delivered from the inside of the film magazine via the film reel-out section, into the digital audio signal recording device via a first film feed-in section, and then transports the film to the analog audio signal recording device via a first feed-out section and a film lead-in section. The motion picture film introduced into the analog audio signal recording device is returned into the digital audio signal recording device via a film lead-out section and a second film feed-in section. The digital audio signals are recorded in the digital sound track area on the motion picture film returned back into the digital audio signal recording device by a digital audio signal recording section provided in the digital audio signal recording device. The motion picture film, on which the digital audio signals have now been recorded, is delivered via a second film feed-out section towards the film magazine so as to be taken up in the film magazine by a film taker-in section.
