We were having a similar discussion on the list a couple of 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...
******* END OLD MSG *********
It's also interesting to note that audio recording went through the same
transition: starting out on drums (cylinders) and then moving to discs.
