Ps2 Backups

[Jacquip]

Hi

I'm new to this forum. Was wondering is it possible to backup ps2 games without a dvd burner like you can a dvd film?
if so what programs are available to do this.
I have bought some copy games which work on my ps2 as it has a chip in it but the games are on normal 80 min disks.
Can you only backup cd rom games and which games are available as cd rom.
