You need to either change your cdrom device's permissions so they are
writable by you, or make the cdrecord binary suid.

The root account is not that different from normal users, often file
permissions is the problem when "it works as root".
I believe cdrecord can gain realtime priority when it's running as root,
but on a modern system it works fine without.
