I am also amazed, but note that a hard bruised CD (from the bottom
side) can easily be polished and read.
I think you can get a polishing kit in the big electronic stores (and
Akihabara) for a thousand yen or so.

CDs/DVDs have thick protective coating, HDD platters do NOT. So you
cannot polish bruised platters, the magnetic layer is gone.
