What we hear in any vinyl album is given by the shape of the grooves.I think nobody ever tried to decode these shapes with microscopes, because it would take too long.
But randomly we can try to cut them ... with the help of an electric toothbrush (or any vibrator), while the vinyl blank is spinning. Would be interesting to hear what kind of music we get from these grooves.
I don't know if that would sound like an electric toothbrush.

If you look at the design of the early recording machines the mechanical microphone - diaphragm - connects directly to the stylus in order to cut the groove. All that changed was an electrical circuit to add sensitivity and drive the transducer.You can demonstrate this by putting your ear close to the stylus of a record player and you can hear faint sound of music - works better with some records than others.
... The idea of the toothbrush I am talking about is not about sounds or microphones, but just a way of creating different grooves shapes randomly ...
