Aren't some organic dyes extremely carcinogenic?  I seem
to remember this from way back when I was working on a Dye laser...

 A CDR will have an organic dye below the layer of metal film.  
 Isn't the organic dye located between the polycarbonate layers?  You
 can kind-of see from the edge that it's a sandwich...  
 I think it depends on the process used to manufacture the CDR 
 disc. I've
 seen some with the dye under a very thin layer of plastic, 
 and I've seen
 some with it directly under the aluminum film. I wish the 
 aluminum film
 was under a layer of plastic tho. If the top of a cd is 
 scratched, there
 isn't much chance for data recovery if the scratch is in a data area.
