The Difference Between Duplication and Replication
The most common question in the CD DVD industry is: “What’s the difference between CD/DVD duplication and replication?”

In the following paragraphs we will attempt to explain, once and for all, the differences between CD/DVD duplication and replication.

An Explanation Of The Three Methods:

1. Single Copy: Also known as a “one-offs,” this is the process of making just one copy at a time on a PC or dedicated disc copier. Making one-offs is fine for backing-up data files and copying music files onto CDs for personal use. But for multiple copies, it’s highly inefficient. Also, using a PC to make multiple one-offs while also running other applications can cause compatibility issues, or slow the computer system enough to create bad discs.

2. Duplication: Commonly referred to as “burning,” this is the process of copying the contents of one CD/DVD to another CD/DVD. The PC or duplication equipment etches the data onto a recordable CD/DVD disc with a laser small enough to be integrated into a normal PC drive bay. CD and DVD burners and media have been a runaway success due to their portability, convenience, and economy. This method is best for producing small quantities of copies (more than one, but fewer than a large commercial run). For quantities less than 3,000, many businesses “burn” their manuals, parts lists, and training videos in-house using DVD copiers such as MF Digital equipment.

3. Replication: This is a manufacturing process that essentially replicates or “clones” the original master. First, a “glass master” is created from the original. Then a set of molds, or “stampers,” are made from the master. Stampers act as a blueprint for the replication process; they are mounted into an injection-mold machine, where a replica of the mold is created in the form of a 120-mm plastic disc. The formed disc is then coated with a micro-thin reflective layer of aluminum. Finally, the disc is coated with a protective lacquer that is first spun onto the disc, then hardened by ultraviolet light. Because replication is complicated, it’s typically considered only for large runs of at least 3,000 copies. At those volumes, replication produces the lowest per-disk cost and offers the highest possible readability levels. In fact, all commercially distributed entertainment and software CDs and DVDs are produced using replication.
