Mastering is the beginning of the CD & DVD replication process. The glass master is produced from our customers’ master source or input media, which can be on a CD-ROM, DVD-ROM, CD-R, DVD-R, Diskette, ZIP or DLT.
Each master source goes through an intensive receiving inspection by our Pre-Mastering department. The master disc is tested on an image verifier (ECLIPSE) and a disc analyzer to ensure that the quality of data meets our customers’ specifications.
A disc of polished glass coated with a photo-sensitive emulsion which is then burned with a laser beam recorder from the supplied input media. After exposure, the data is developed and saved as "pits and lands” (the digital ones and zeros). This is now called glass master.
The next step in stamper replication is where the glass master is electroplated with nickel, then separated from the master. This forms a negative known as the "Father" stamper. For large runs the "Father" is plated to produce a "Mother", and from a "Mother" many "Sons.”
