CD and single layer DVD can be stamped on the same gear. The only
difference is the master.
BluRay is multi-layer out of the box which is like asking for
problems. And regardless of the fact that it followed the diameter of
the form factor I mentioned, it has followed nothing else about it.
Why do you think the number of four layer DVDs is so low? Could it
be "Prime Pass Yield"? Another term you'll have to look up.
