Hi Sam
You are both right. The CD is read through the bottom material
that is thicker. The top side has a think layer before it actually
reaches that data part. The thickness of the bottom improves
the ability to read through small scratches since the surface
is farther from focus ( Hold your finger up close to your eye
and look past it at something a few feet away. Notice that you
only see fuzzy shading caused by your finger. ). They take advantage
of this to see through small scratches.
A good sized scratch on the top can go right to the data layer.

Apparently the actual data layer is located very
near the label face
of the disc. Hence, the outer layer of the see-through face is quite
thick, and you may remove some without damaging the data. It worked
quite fine in the review.
Ok, so I've been reading all the replies on this. And from what people
are saying, I'm lead to believe that scratches on the non-label surface
have no effect on the ability of the CD to be read? This goes totally
against my experience with CDs, so I'd appreciate someone clarifying this.
I'm under the assumption that I'm going to rub Colgate on the non-label
side of my CD and then rub it circularly until the scratches are
diminished.
