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.

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.
