REPLICATION VS DUPLICATION
Replicated CD’s are created by physically pressing your data onto the surface of the disc. Duplicated discs encode your data onto the disc by burning microscopic holes into the dye layer of a recordable CD or DVD. Most major commercial releases are going to require CD replication.

Replication is most cost effective on orders of over 300 discs, and offers more packaging options. All major commercial release will require that your release is replicated. Duplication is most cost effective on orders of fewer than 300 discs and can be significantly faster than replication on shorter runs.
