For the DVD+R burn:
You have some good discs [as long as they are genuine YUDEN000 T02 discs–it looks like they are], and your DVD burner isn’t the worst DVD scanner, so you can get some idea of your quality. Your burner paired with those discs should be a winner. Just note that because they’re “only” 8x discs does NOT mean that they are bad; YUDEN000 T02 is considered one of the best discs models of all and is consistently slightly better than its 16x counterpart [YUDEN000 T03].
For the CD-R burn:
Your Daxon CD-R are known as being OK discs; not the greatest, but being pretty good. With your particular burn, the disc quality scan is pretty acceptable, and the drive is a pretty good CD scanner and burner, as far as I know.
Try writing these CD-R at a more “reasonable” 32x, 24x, or 16x, and the scans might improve a bit for you.
Also, the TRT of the discs are perfectly clean, with no drops/dips other than those imposed by the drive in all normal TRTs. This backs up the “good quality” reflected by the disc quality scans.
