These errors believe it or not are simply because of not being the root user or running with sudo! However if you didn't know to try as root you'd think there was a problem with your burner or disc Essentially it looks like without root you cannot send the required scsi commands to continue writing. I think cdrecord should have built-in tests or safeguards to see if it has the permissions to run the required commands.
I guess for more advanced users the idea is similar that you cannot do a dd from a device without being root usually.

Simply run cdrecord again as root or with sudo:
cdrecord -v linuxmint-18.1-cinnamon-64bit.iso
