A glass master is pretty much what it sounds like. This is a master mold that is made from your master Cd. This mold is then used to inject the melted polycarbonate granules into it. This glass master already has all of your electronic media stored into it. How is this? Picture a record and remember how the needle on the record player would be placed into the groove of the record and it would then send that signal to be amplified so that you could hear it. The grooves that the needle was in had very small changes that would determine the frequency to be amplified. To better explain to the non tech individual, imagine that you are driving down the road in your car, (you and your car represent the record player needle), and the road you are driving on, (the road is a representation of the grooves in a record), and imaging that you have a bell hanging from the rear view.

You can think of the glass master as the first "mold" in a series the replication plant will create in order to arrive at a "stamper", which is what is used for the creation of the final "pressed" disks. Just as burn speed is important in the creation of a CD-R, the best "pressed" disks result when the glass master is cut at real-time speed (1x). It is a good idea to ensure your manufacturer of choice will burn the glass master at 1x.  more
