Rename CD?

Hi,

I just copied my tax returns to a CD, but I named it incorrectly. I'm trying to rename it by clicking on the CD title that is shown as it appears on my desktop (the same as I do with a regular file), but it won't shift to the mode that allows me to change/retype the title. I can't find anything in Mac Help, and there's nothing in the dropdown menu for finder to rename the CD. Any ideas?

Thanks,

Esther
