This article is from the CD-Recordable FAQ, by Andy McFadden (email@example.com) with numerous contributions by others.
There are a large number of companies that will do modest production
runs of pressed CDs, but listing them is beyond the scope of this FAQ.
Do a web search on "CD duplication" and "CD replication", or check out

site from the www.cd-info.com folks).
Sometimes a disc submitted for duplication will be rejected due to E32
(uncorrectable) errors. If you have a disc rejected, make sure you are using
disc-at-once recording mode -- the gaps left between tracks by track-at-once
mode are sometimes interpreted as errors. If the problems persist, try
changing to a different kind of media, or even a different recorder.
