DVD+R Discs Burn Quality at 16x speed

MSI DR16-B2
 

BenQ DW1620 
 

And finally we got to the maximum, 16x burn speed. The MSI DR16-B2 has shown good results so far, but it couldn’t do the same in this test. The PI Error rate is normal, but higher than at the lower burn speeds, and the density of PI Error blocks is higher, too. The same is also true for PI Failures. At the end of the disc, however, the level of PI Failures exceeds the norm. I should note that the BenQ DW1620 also had problems at this burn speed with its older firmware versions. But like with CD-RWs, the release of the version B7T9 firmware changed the behavior of the device dramatically – now this optical drive delivers an excellent burn quality at 16x speed.

Beta/Jitter and TA Test for the DVD+R disc
burnt by the MSI DW16-B2 at 16x speed

The Beta and Jitter graphs indicate that the disc recorded by the MSI DR16-B2 drive is far from perfect. The reduction of the laser power at the outermost tracks didn’t led to catastrophic consequences at the lower burn speeds, but now it results in a dramatic outburst of errors, a growth of jitter and ultimately to the total unreadability of the outermost tracks. The results of the TA Test agree with that: Jitter is very high for small-length pits and lands, and the Peak Shift value is big, too. So, until the manufacturer corrects these problems in firmware updates, there’s no sense in using the maximum burn speed since it brings you a very small time gain over 12x speed, but worsens the quality of the resulting disc too much.
