Replication is a manufacturing process. CDs are produced in 2 steps:
Step one is mastering. A glass master is created from a digital file. The glass master is used to create a metal stamper, which contains the digital information.
Step two is the injection molding of the discs from the metal stamper. Molten plastic is injected into the target mold containing the stamper. Seconds later a clear disc containing the digital information is ejected. The clear disc then has a reflective and a lacquer layer applied.
CD-Text is an extension of the Red Book Compact Disc specifications standard for audio CDs. It allows for storage of additional information (e.g. album name, song name, and artist) on a standards-compliant audio CD. We can add this infomation to your CD for a small fee, or you can deliver a master with the text already attached. More info
