Not to be pedantic, but I must submit a minor factual correction:

The pits representing digital information on mass-produced CDs, CD-ROMs, and DVDs are not produced by laser (burning), but are literally stamped. The final master CD which the factory receives from the mastering house -- which *is* actually laser-burned -- is used to produce the die, or what in the music industry is known as the "glass master".

This stamping process is obviously a little less expensive and much less time-consuming than burning on a mass production scale.

Here's a further explanation:
