No, no, and and a big no.  CD-R and DVD-R media cannot be written to 
like a normal block device. (I never realized how counter intuitive that 
was before.  I guess you had to be there when they first came out :) )

Try using cdrecord instead.

cdrecord dev=/dev/scd0 -v -dao cd.img


Note: in the future, if you need to grab an image of a cd, name the file 
  something.iso  Ubuntu GUI will recognize .iso file extension as a CD 
image and will do the right thing with it on a right click.

Note 2:  This probably won't have desired results on a music or mixed 
mode CD (CD's with music tracks as well as a data track)
