illegal or not?

[battybackup]

sorry if im repeating previously asked questions, but:-
my old ps2 laser mechanism broke and burnt my lma2005 disc and made it unreadable. i downloaded iso from a warez site and burnt it off to replace my ruined disc. was this breaking the law?
i thought that as long as i owned the origional disc this was ok?
after all im alowed to make a backup of my disc. aint i?
this was all done 12 months ago so its probably irrelivent now but i just read a post by suggsy and now im not sure if what i did was illegal or not.
does this law vary depending what country you live in?
i hope asking this question is not breaking the forum rules but i need to know to avoid and future problems.(the missus would go mad if the police came knockin at the door). surely if what i did was illegal i would have been contacted by now?
