Can I backup music CDs onto DVD-R's?

I understand that one way to backup a music CD that I own is to “rip” the CD to my PC, then copy it onto a CD-R.
But I am wondering about the possibility of putting the music of several CDs on a single DVD-R, since a DVD can hold a lot more data than a CD. Can this be done just as easily as writing onto a CD-R, or is there a special “trick” involved?
