Problem, Please Help

I was backing up my computer today onto CDs and I deleted most of the files after I was done before I was going to re-format. It turns out two of my CDs did not burn properly and I lost the info on them and some of it is very important for school work. I am running winXP with NTFS, I know you can do this in fat files systems but wit NTFS is there a way to restore deleted files? I have not formatted yet. Can I roll back my registry or something, I tried windows restore but it only restores important files.

Anyone who can help please respond.
