CD ROM Duplication and CD ROM Replication

CD ROM duplication or CD ROM replication necessitates availability of the media, the CD ROM, on which the data, the audio or the video is duplicated or copied. The increase in the CD duplication, i.e. consumption of CD ROM for various purposes, gives rise to the demand of CD ROM duplication or CD ROM replication. CD ROM could be of 'write once and read many' type. CD-R is another name of CD that already has the contents written on it and is can only be used for reading purposes.

Just as there is a difference in CD duplication and CD replication, a similar difference exists between CD ROM duplication and CD ROM replication. While CD ROM duplication is a simple process that you can perform with a PC with a CD writer, you need a special machine for CD ROM replication.

CD ROM duplication involves recording of data on the disc by laser. Laser is aimed into a dye that lies above the substrate and the reflector - the shiny layer that sends the modified laser signal back to the CD ROM device. CD ROM duplication is a slower process when compared to CD ROM replication because you can duplicate just one CD at a time with duplication devices. However, with CD ROM replication service, you can achieve faster copying and production.

CD ROM replication involves creating a glass master, which is then used to physically impress the information on the plastic during the manufacturing process.

The important feature of a CD ROM is its speed. The speed of the CD ROM determines the speed at which the CD ROM duplication can be done. The speed may vary from 4x to 52x. Therefore, the throughput of CD ROM duplication depends on the speed. You should select CD ROM duplication if you want to create a few CDs and opt for CD ROM replication if you are looking for mass production.
