In hindsight it looks obvious. I'm not convinced that it was
obvious 50 years ago.
I can imagine a couple of engineers in the 1950s hanging out at the diner for lunch and
discussing "we need something with capabilities similar to drums but with a lot more
storage capacity".
One of the engineers gets up from his seat and puts a nickel in the jukebox, and watches
the tone-arm move amongst the stack of disc records...
