What is a CD?
The CD (Compact Disc) is an optical disc used to store data. Today it is most often used for music as the DVD & higher capacity has all but replaced it as a data medium for computers and interactive games. The CD is capable of storing up to 80 minutes of audio or about 700 Mb of data.
The CD presents as a disc 120 mm in diameter and 1.2 mm thick. It is a single layer of poly-carbonate plastic with a single layer for information. The plastic is molded with the information and a thin layer of aluminium is added to create the reflective surface. A layer of lacquer is spin coated onto the disc to protect it from damage. Then the label is printed onto this lacquer layer.Smaller CD’s are also available. Mini CD’s are 80 mm in diameter and can hold about 21 minutes of audio. Business card CD’s are discs that have been cut into unique shapes and designs for marketing purposes. These discs are usually meant to hold marketing information such as brochures and presentations rather than audio.
Replication versus Duplication
At PROLINE IT we offer clients CD replication and CD duplication services. The difference lies in the method used to create the discs.
CD replication is the process used for the manufacture of all copyright material such as music, movies and games. A glass master is created and it the CD’s are molded. Replication is very cost effective for a large number of discs or where the protection of the information is important. CD duplication on the other hand is the process of copying the data from one disc to a recordable disc using a writer or burner. Most people with a home computer will recognize this as the process of burning or writing a CD. This process is useful for a small number of discs. CD duplication is useful for people who want to burn a large number of discs for personal reasons like an interactive photo album of a wedding.
