You have a simple verify error near the edge of the disk. Could be the disk, the drive or firmware.
Update your firmware - http://forum.rpc1.org/dl_firmware.php?download_id=2210
And, if possible, select the layer break closer to 50/50 (this would have burned only to about LBA 1,762,000 and then got to layer one, eliminating the more dangerous edge of disk).
