Wavelength response of first type of film with sound?

Hi: What wavelengths of light specifically affect the type of film used in the first movie containing an variable-density optical audio track? I am specifically interested in the chemical composition of the optical audio track. From what I know, most of the more modern films are unaffected by red light. I'm thinking of a theoretical device using analog audio recording on VD optical tracks containing the oldest film chemical composition. The source of light are multiple laser beams consisting of wavelengths that could record the audio onto the film. Each beam has a different wavelength. The beams are then mixed together to get a single beam of all the necessary wavelengths. The beam then shines onto the film to record the audio. I don't have much of an application here. I'm just in it for the science. Thanks Are you sure you aen't related to Hughes/Eugene? -- Regards, Savageduck |
