Not exactly, cdrecord is complaining about not having exclusive access.

On mine when I insert a blank CD it automatically loads the nautilus
cdcreator to burn a disk.  I have to close that b4 I can start a burn

You also cannot mount a CD with a filesystem on a device that is being
held by some other process (such as nautilus).
