HD-DVD Disks - Are they supposed to look wavy?

[aphex]

I was jyst looking at two of my HD-DVD disks and notice they almost look as if they are wet, kind of an uneven wavy-ness consistency to them...

Is that normal?

Mine look like that too so, I guess so.

The more waves the better. And yes, that's normal. Blu-Rays look the same.
