Creating a copy of a CD Image

Hi all, I know that the answer to this is easy, but I can't seem to figure it out... I have a data CD, and I want to make an iso image of it so that I can upload the iso image to another storage location (fileserver, for example). I looked mkisofs, and I think I could use this tool, but is there another, more direct way to get the CD image? Thanks, -ronc
