There's a great segment on LP manufacturing on the show How it's Made on the Discovery Channel. Lots of great photography of coating the aluminum substrate to make a lacquer, through disc cutting, pressing, and all the way to packaging.
Robert, I seem to remember a guide in a record collecting book somewhere in my travels on how to read the codes in the run-out grooves of a record. Surely this must vary widely depending on the label and the pressing lab staff, but is there anything published that you know of? How does one interpret that information to determine which stamper or mother was used? Obviously one would want the lowest number possible when buying a used record.
Thanks!
