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?

. The linear speed of the tape is 7.5 ips (19cm/s) and the quality is pretty good with surprisingly little surface noise. The cartridges were available in 30, 60 and 90 minutes playing time which, in the 1950s, the time of these machines, was extremely good and led to them being used in "kneipen" or bars and cafes. Very good little machines and there was even a wired remote control which enable tracks to be jumped or repeated!
