how Compact Disc are produced

You have two technologies available to make your discs -- pressed discs or recordable discs. It really depends your needs.

Pressed discs refers to the manufacturing of CDs or DVDs by  1) pouring out substrate into a mold to create a disc, and  2) making a glass master/ stamper from client’s cdr master and using that to PRESS data onto the manufactured disc.
• Pressed discs are suitable for large runs (>1000).
• Discs can be silkscreened or offset printed.
• Often referred to as pressing, manufacturing, or replication.

Recordable Discs

Recordable discs can be made by first pouring out the substrate as above, but then adding a special layer. The end user can then burn or RECORD data (using a desktop cdr writer or cdr drive) onto the disc.
• Recordables are more expensive to manufacture than pressed discs.
• Recordables are suitable for short runs (<1000).
• Discs can be silkscreened for professional appearance.
• Packages with recordables are generally unassembled (without shrinkwrap) for ease in client burning (note- we do not do any burning of client data).
• Typical uses- frequently changing data or individualized discs.
• Often referred to as burning, writing, sometimes duplication.
