1. Some Taiyo-Yuden (and possibly other) discs have such a unique number.
Some disc lines have a code in that area to indicate lot number. Most media
have nothing there at all.

2. That code is rarely sufficiently legible for many purposes. In
particular, T-Y uses fine, light printing, visible only when the disc is
held to the light. Finding a misplaced disc requires removing each
candidate from its storage, more handling than one would wish.

It makes sense to use a unique identifier in that area. In fact, I
suggested just such a solution, writing whatever is appropriate. I do so
regularly, using a water-based ink from a TDK "CD Mark" pen in a color
which can be used in the code (e.g., red - master, blue - submaster, black
- dupe).
