First Generation CD's
SRC pressings
https://www.discogs.com/forum/thread/415150
SRC began using a Code 39 barcode sometime in 1990 and continued until the Cinram merger in 2003. However, many discs pressed from mid-1992 to mid-1993 do not have a barcode, and after that, the blocks in the barcode were narrower/thinner than before, as they squeezed in another character in the same amount of space.
