Rca Victor records manufacturing process 1942 part 2

Thanks for posting this great video. It really show what goes into making a record! Looking today at the process, I always think it's a miracle that the record even played. The background music was too funny - as one person already commented a real 'american industrial film!'

Wow! this is great. Reminds me of those "industial films" we used to watch in school w/ the old bell and howell projector..

what kind of crazy auto change was THAT at the end !? obviously it didn't catch on, probably smashed your records up.

Good question!!! I can see this type of thing in a jukebox of its day, perhaps, but a home record player?

some of the really old 78's were only single sided and almost 1cm thick!  I remember back in school one of our teachers brought his old gramophone and some 78s in to show us and I've been facinated with the old records ever since.

I actually own a 78 album now, from 1945. 4 records, 12" double sided.

I know about the single side original pressings: gotta wonder how long it was before someone really did try to put sound on both sides (thus giving the disc record a leg up over the cylinder).

They feel so.. unique. Too bad 2 of my 4 are broken, but thye sill play. Then again, its not really good to play them on a turntable setup that is not made for them.

The thicker 78's were the Edison discs. They're different from the Victrola ones. The Edison discs sound better, see for yourself. Some have uploaded clips to Youtube.

It looks as if making records was just as complicated back then as it is today, if not more. I have some old 78's, but I cant play them as I don't have the right stylus and my turntable is only for the 33 and 45 rpm records. Can anybody tell me why the center groove on a 78 is off center? It's puzzled me years.

The off center groove is called the 'eccentric groove' and was detected by automatic record players to trigger the reject mechanism. This was done so that no friction was required that would cause wear to the playable part of the record. Where normally, the grooves move toward the center, it is when the eccentric groove moves away from center that the reject mechanism was triggered. It's rather simple, yet brilliant.

That's why they only had "listening jobs", "polishing jobs" or "packing jobs". Nothing Too strenuous haha.. (just kidding before anyone one gets offended)
