Remember LPs? Well, I sure do -- over the past week I've been working on digitizing some LPs that haven't been (and perhaps never will be) released on CD. Below are two videos showing how records are made -- first, the laquer Master Disc, then the vinyl copies you and I buy at the store. I believe these videos are from the Canadian documentary series How It's Made (the other items from the same episode included "bagels" and "chains") shown on the Discovery Channel in most markets.
The Laquer Master Disc
The Vinyl Copies
Check out the silvering process on the master -- that must be expensive.
