Backing up Ps2 games??

[rubrides]

I hear that alcohol is the best program to use for backing up Ps2 games, and that Ritek is the best (dvd-r's) to use when backing up. I was wondering if it was possible to back-up PS2 games on Cd-r's? If so, how do i go about this and do you get the same quality game if i do so? Are there any drawbacks to backing up PS2 games on Cd-r's and can all Ps2 games be backed up on cd-r?
