The recordograph

[big band heaven]

Here is something I haven't seen before or even heard of. I came across this excellent website last week and it details a machine that records onto camera film. Not in the way you would expect though as instead of doing it optically it instead cuts a groove into the film itself. Not sure what the quality would of been like - but I thought a novel method of sound recording.

Here is a link to the website with photos of the machine and diagrams showing how it records onto the film. Has anyone ever seen one of these machines? Or even heard of them before?
