What is the name of the CD drive?

I'm taking an online graduate course, and they have sent me a CD-ROM with a audio lecture and accompanying slide presentations. The preferences part of the online BlackBoard class environment prompts you to identify the cd drive on the computer to make these things work. For a PC, it would be the "d" drive, just as the internal HD is the "C" drive or floppy drive is the "A" drive, etc.

So then they say with a MAC you need to input the "name" of the cd drive. So what's the name? I have looked in the system profiler and it says nothing, I have checked the "path" of a cd mounted on the drive and is says "/volume", but this still doesn't work. Anyone know?

Fortunately, I have a backup PC that can run these things, but it would be useful to solve the problem and make it run on my Macs.
