Also note that all CD-R are not equal to scratching too, the color tint 
of the CD can give an idea
no color ? poor dye layer
Gold is usually used in conjunction of of a good quality dye, but not 
always. (on the read side not on the label side ...)

Markers (those we all use for our CDs) can damage the layer as the ink 
could make it to the data layer.

Also Oxygen can reach the reflective layer, silver and aluminum 
corrodes, damaging the reflective layer (keep you CD-R in a safe...).

There is usually no way to know if the manufacturer have added a 
protective coating to resist scratch or if your CD are scratch prone, 
just a question of luck.
