Try another blank (also from a different make/batch, or possibly a cdrw
first?)  When I got something like this once the blank had a media defect
that was even visible to the naked eye...

 Of course the drive could be dieing too, apparently today's drives don't
last for as many writes anymore as in the past.  (Chinese mfgrs cutting
corners everywhere I guess...)
