Mastering Technology
Glass Mastering is the process of transferring the CD master to a physical image of the pits that are on the finished CD. The glass master is a glass plate, about 10" in diameter, coated with a light-sensitive material. During glass mastering, a laser etches very tiny pits on the material. When the master tape is played, its digital signals are converted to the EFM coding format for the CD, and that signal is fed to the special laser cutter. The glass master is very delicate, and cannot be played. Succeeding steps in the process, called Father, Mother, and Stamper, result in the metal forms which are capable of hot molding thousands of compact discs on the presses. |
