PDFs on your website are a treasure trove! So, the picture was "painted" on the master film by an electronic beam. Then copies were made by optical duplication. Then the picture was be scanned by an electronic beam again and converted to TV image. It is an interesting blend of analog electronics with film tech. I applaud that 60 fps was chosen to preserve as much info as possible.
Considering how magnetic tape, HDDs, memory cards age over time, maybe it makes sense to reconsider using film for long-term storage? Actually, I think optical discs are the best for long term, but I am very afraid that soon there won't be any CD/DVD/BD readers.
For black-and-white version, have anyone thought that the second track should start at the end of the film, so it would work like a regular audio tape: play track 1 from the beginning to the end, then switch to track 2 and play in reverse. This way you would get 50 minutes of moving picture with just a small blip in the middle.
