Rip an audio CD 1:1

Is there a way to rip an audio CD to an ISO9660 file? I've tried simple things like dd in the past and it hasn't worked. I'd like to essentially have a mirror image of exactly what's on the disk, not even necessarily a folder of WAV files. I do understand that I could rip the CD to WAV files or even FLAC files, but is there a way to just duplicate the disc to one file, so I could extract WAVs or FLACs from it later on? The idea is to be able to make a virtually identical copy of the source media.
