Sounds like you've got a scratched or dirty disk. Try giving it a clean. Hold by the edges, making sure your fingers do not touch the disk surface, then use a clean cloth and wipe from the centre outwards - not in a circular motion. The other possibility is that your PlayStation disk drive isn't working properly - that could be a hardware fault or just try resetting the console. You could also have a game from a different region. If the game is an import game, it won't work on your PS2.
You probably need to clean it.
