For a single track CD (DAO) dd works fine, and quickly. You can try
sdd or readcd (read the man page carefully!) if you have any problem. If
the CD is audio, I highly commend cdparanoia, which has been quite
successful in extracting data from less than perfect CDs, including one
bad factory press (single run and not replacable) which had tracks no CD
player ever played.
For a commercially pressed data CD I would use DD to disk and then
burn. People do pipe CD to cdrecord, but using dd may have errors, and
using any error-correcting program may delay data and let the fifo go
enpty.
