CD replication and CD duplication are two different processes that are easily confused. In the process of CD duplication, data from one CD is copied onto many other CDs with the help of a device called a CD writer or CD burner. CD duplication involves burning data onto a disc and is often carried out using domestic pc equipment.The process of CD duplication can also be used for creating backup copies of your data, including films, music, games, photos, files and documents. However, duplicating CDs at home will not produce the best results, which is why opting for a professional CD duplication company is a great idea.On the other hand, CD replication is a process that produces a CD by molding the disc from a stamper, in order to create a duplicate of the master copy. Once this process is complete, the data on CD cannot be changed. Whilst CD duplication is ideal for creating less than 500 copies of discs, CD replication is ideal for creating more than 500 copies. The process of CD replication is often used by software companies, music and video companies and promotional companies.So, take a look at your requirements, and decide whether CD duplication or CD replication is the most appropriate.
