I always thought the Videodisk (and Phonovision for that matter) was such a cool idea. Use the same thing as what you’re already using to record music. No need to reinvent the wheel. It’s nice and efficient. Sadly, the former never caught on and the latter was just experimental.
Another thing that’s always intrigued me about it is that not only is it “analog”, it doesn’t even require electricity, at least for the audio portion. Sound waves could mechanically move a needle through warm wax which was spinning on a turntable at a regular rate with a hand-turned crank, across a screw drive. That needle would leave a spiral groove in a wax disk (or cylinder) that could be cast in metal using the “lost wax” method of casting. The reverse process would occur during playback, when the needle would read the data that was already recorded, and vibrate a mechanically amplified tympanum. I still don’t know enough about the image recording process to say whether that could be done without electricity, but I know that its inception and the development of electricity happened very close together. There’s no real reason I can think of why the Ancients could not have made something similar for recording audio and playing it back. The first phonographs did not use electricity!
I had this dream once of operating an early electric style studio. Not pre-electric like the first phonographs (one studio actually had a rope going into a well to spin the cylinder!) but all 1930s-era technology and recorded straight to disc. I think some musicians could really go for it. But I never did it.
Also, I am stunned that, within my lifetime, we have gone from being able to store 30 minutes of audio on one side of a vinyl disc, to over an hour on a CD to hundreds of hours on an MP3 player, to unlimited streaming almost anywhere in the world today.
