I can scratch your cd dad watch me.....(makeing dc backup is it possible?))

I have a 2 year old who tries to play my dreamcast while I am at work and so far he has scratched 4 cd's 2 of them I can still use and the others are used to play with or toss like a horseshoe. How can I make a backup copy of my other games and keep the originals away from him and let him play with the backups. What software do I use Or is there a certain burner just for that?
