There is some information about the ill-fated Cinema Digital Sound (CDS) system on-line: http://members.aol.com/cds3570/ http://www.moviesoundpage.com/msp_cds.htm Kodak was very involved in proving the design concept of being able to print the CDS digital soundtrack on the film, and in marketing the system and implementing it in the film laboratories. But the hardware design was not Kodak's. The decision to put the 35mm CDS track in the analog soundtrack area to minimize wear from the projector was the right one technically, but the lack of an analog back-up track doomed the system when there were hardware problems. Give CDS credit for starting the "digital sound revolution" with a bits-on-film system that worked very well, except when the hardware overheated. Without this pioneering effort, the move to digital sound would have taken alot longer. ------------------ John P.
