New vinyl's noisy little secret

I may be wrong, but it seems to me that the current crop of vinyl formulations just have higher noise levels than LPs made years ago. A case in point--I stumbled upon an old, original copy of Henry Mancini's 1962 soundtrack to the movie "Hatari" in my collection a few days ago (I had never even played it), and was astonished at its deathly quiet playback. Simply no surface noise. What gives? OK, you may make fun of this black-label RCA pressing (LSP-2559) for its content musically (though it's actually pretty fun), but it sure reminded me what we are missing with new releases--super high quality vinyl with very low surface noise. Even the occasional mechanical clicks from scratches seemed subdued. Most of my (expensive!) new vinyl comes replete with very onerous surface noise. Is it just impossible to make this old-generation type of vinyl currently?

Exactly! I always thought the name "Pop Pop" was a little more than ironic. Terrible pressing.

Thank you Axel for the great explanation. I found out about 78 rpm metallic masters from the NY Times article this past Sunday. Paramount Records in Wis. evidentley used these back in the 20's and 30's for their Blues artists. They have never found these original metal masters, some saying they were melted down for the war effort, others thinking disgruntled workers threw them into an adjascent river after the factories closing (divers have even scoured the bottom of the riverbed looking for them)
Check out the article (there is a link posted on the music threads)

that's funny and sad at once.
I was NEVER aware that direct(was it?)-metal-mastering was already done in the 20s - 30s!

In fact, I have no real knowledge of the actual process. All I understand is, that in place of a lacquer (cut with a diamond) a metal disc is cut from which then the stampers (I guess!) would be 'pulled'.
This cuts down a couple of steps from the normal process. But that cutter (of the cutting lathe) will have some tough job, and I guess plenty more diamonds will be used.
In fact, that disk would have to be non-ferrous (some alu-alloy mix I guess) since one can not use diamonds cutting ferrous metals.

Cheers,
Axel

There's a bit of misinformation in this thread. If you want to understand the pre-tape "mastering" process, watch a two-part video on ewetube called "Rca Victor records manufacturing process" and you can see it for yourself step by step.

Actually this is interesting as today I picked up some old (second hand) vinyl from my favourite charity store and playing one of the records this arvo, I realized that despite the occasional click and plop, the basic noise (vinyl) floor was very low and considerably quieter than more recent vinyl records.
