I may just be totally missing something here, but what is a silver pressed CD?

Re: Silver pressed CD?
a cd that's not a cdr. they're Silver, whereas cdrs are gold or blue or something. Silvers are more durable.
For example, a legit cd you get at the store is always a "silver" I'm sure somebody will have more to add to this...

Re: Silver pressed CD?
Basically, a writeable CD, or a CDR, contains a dye that is aligned with a laser to construct the data layer of the CD.
A silver pressed CD actually contains a physically stamped data layer, making it much more durable. It also means that it's an original and has not been through many generations of potentially flawed extracting and re-burning, which is why we prefer to have seeds from original silver pressed CDs seeded if possible. Take a look at your original discs, and notice how they are silver compared to the green or purple or blue of the dye of your CDR. If you really want some insane detail on the subject, here's an awesome link to everything you ever wanted to know about audio CDs: http://www.cdrfaq.org/

Re: Silver pressed CD?
2 biggest differences between CDR's and Stamped Silver CD's are:
1) CDR's Dye Layer is suseptible to deterioration due to exposure to light and because the upper surface is thinner and less durable than silvers. 2) Stamped disks have clearly defined perforations that the laser then reads as 1's & 0's (or pits and lands to be more accurate). Unlike the precise holes created in the stamping process, if you look at the laser burned holes on a CDR through an electron microscope (lemme open my desk draw here and get mine...... ahh.. yes, there they are ), you'll see that they're very ragged and imprecise. This causes errors on decoding, which means that Reed Solomon error correction needs to work much harder to decode an audio disk that you burn on your computer. There is built in error checking when you do data disks, so the laser can go back and re-read sectors if necessary. Ditto the McFadden FAQ that RainDawg has pointed you to. This document has been carefully tended, and drawn from many sources, but mostly from the pioneering Usenet groups that dealt with burning stuff to disk. It's invaluable knowledge if you need to know this stuff. No members have liked this post.

Re: Silver pressed CD?
One major difference is as well that a silver disc in general comes from a glass master while the CD-R comes from an extracted format that then goes through the process indicated in the cdrfaq.

Re: Silver pressed CD?
Now that I have this cleared up, I wonder what would be sourced from a silver-pressed CD? Since official releases are not allowed to be spread, I cannot think of other things that might be included.

Even today you can walk into just about any music store and find dubiously licensed material by non-mainsteam artists pressed on silver CDs which presumably would be okay to trade. I would guess that shadier stores and online outfits still actually sell silver CDs of big name bands. CDRs have made it easier for bootleggers to do 'garage' operations and make their own, but it also has lowered demand, because anyone can make their own CDs -- hence, places like this. CDRs are even so prevalent I know one record company that (frustratingly) only issues new releases on CDR. No members have liked this post.

Re: Silver pressed CD?
Most discs are now produced in Eastern Europe. Indeed, the most annoying problem is that these companies now release these discs as cheap CD-R with low quality artwork at the same prices

Re: Silver pressed CD?
If the media is Taiyo Yuden, Verbatim, or recently made Ritek, I don't think you have to worry about potential skips/gaps/etc. That media is quality. But I realize most CD-R's out there are not, so I understand the rule.
