I do believe that Alan Blumlein's first experiments with stereophonic sound recording used optical methods on film. The only other viable method would have been disc recording. Perhaps he thought the sound quality was better, or perhaps it was just easier to have two separate tracks for the two channels, synchronised to within a few hundred microseconds, than would have been easily possible with disc.
