In black and white it looks like they're making crepes. Very interesting video!

Most interesting bit: The label is pressed into the record, not just glued on.

Looks like the only things that changed really, between the 78 and the LP vinyl era as far as the manufacturing process goes is that with the invention of the tape recorder, recording studios could finally be completely separated from the manufacturing plant, allowing for much more freedom in recording selections, and the actual presses were fully automated.

Fascinating. I always wondered how it was done. Lots of chemistry there. RCA had a plant in Camden, near me.

Very cool! Also take a look at the movie on the sidebar marked "trash those records". I never knew they used to make giant cassettes! John

I've yet to watch part 2 but there is a lot more to making a record than I ever thought. Who the heck was smart enough to think the whole process out. Wow is all I can say.
