Gamecube action replay discs degrading

Drilling a small hole at the end of the crack will also stop it I was told. I still don't see how it would. It's how windows get stopped from cracking up.

Many games I've hired had this problem too, also many demo discs suffer from it, some how.

 

Had a lot of call of duty moden warfare 2 discs go like that been though about 6 of them.
