I've always assumed that Sound on Disk was Western Electric's brainchild, whilst RCA Photophone was a sound-on-film system.
But here we have a disk clearly marked as Sound Recording by RCA Photophone System.
This is somewhat of a mystery considering W.E. and RCA were competing sound systems, with RCA's sound-on-film the eventual winner.

What a fascinating couple. But what will happen to their collection as time doesn't appear to be on their side.

The marking on the disc "Sound Recording by RCA Photophone System" is indeed true. The soundtrack was recorded sound-on-film and simply re-recorded onto disc for theaters not equipped for sound-on-film reproduction. Photophone means "photo" as in optical track being photographed on film, and "phone" as in telephone technology used in the system. RCA Photophone was, indeed, a sound-on-film system originally using a unilateral variable area photographic record.

Western Electric's variable density sound-on-film system became the industry standard shortly after the introduction of their sound-on-disc system. Even Warner Bros switched from sound-on-disc to sound-on-film by 1930, still using their "Vitaphone" trade name.

Thank you, Kenneth.
I understand that many cinemas who had invested in Western Electric's sound-on-disk system were reluctant to spend more money on the newer sound-on-film system.
For that reason Western Electric kept their disk system active for quite a few more years.

That was a very interesting video. I love his proscenium and would love to build something like that myself.
