Looking here and there on cdfreaks forum I found different opinions and facts about RITEKG05 media, spanning from total disasters to decent burns.
So I tried myself with a NEC 3550A burner to see if these media are good enough for my backups. Unfortunately my scanning device is the nec above, so I played with different speeds to see if things changed.
These graphs refers to the same RITEKG05 media (sold as Ridata DVD-R 8X in a spindle of 50 discs) burned at 6x (look, six!) and scanned at 5x, 12x and Maximum (16x).
BTW the 5x scan is a complete nonsense (and this isn’t the first 5x scan that goes out as a nonsense, even with different media!) , so I think this burner is totally unreliable scanner at 5x!
Also if someone has a nec 3550 (or 4550, that’s the same) ritekg05 media and a good scanner, can please post here some quality scans?
