Then you'll have to use the blocksize of the CD (in most cases 2048):
dd if=/dev/cdrom of=/path/xyz.isofs bs=2048
That usually should give you an usable ISO image. If not, you have to
count the valid blocks and tell dd about them, too.
df
# get the number of blocks - watch df's block size! Most times 1024!
dd if=/dev/cdrom of=/path/xyz.isofs bs=2048 count=<number of blocks>
