Weird Starting Problems for Disc 3

This past month i have been playing FF VII again. So I finally get to disc three, I put it in and the screen goes black and makes an weird "error sound" (hard to describe, its like when you select something wrong in the game it makes sort of a beep). So I reset my PS2 and after the opening credits it does the same. After trying this on my PS1 and PS2 I figured it was the game. After buying another copy of the game it does the exact same thing. Neither discs work on either system.

Has anyone else experienced this weird problem? Thank You in advance.
