strange problem with gamecube disk(super smash bros melee)

[Xyn]

After playing too much Brawl, I decided to play Melee. Yeah I put the disk in my Wii, clicked on my disk channel and pressed START.
Well I chose to play in 60 Hz Mode(like always) and then the game checked my non aviable memory card, so I pressed no to play without saving and then . . . "The game disk ccould not be read, please read the game instructionto get help"

That was very unexpected. Even burned games could be read by my Wii
