Pioneer DVR-112D - burning at 12X
-The reading process
Both sets of measurements report a major spike at the same position of the disc. Notice that the X-axis on the Datarius graph indicates radius (mm). More importantly though, is the fact that according to KProbe, this burn is within specs, whereas the DaTARIUS Analyser clearly shows that PISum8 has exceeded the acceptable levels.
Looking at the Nero CD-DVD Speed graph, it is nice and smooth but there is a tiny downward spike around half way which corresponds with the KProbe graph. This clearly shows that these measurements are in the main, dependent on the drive being used to do the reading.
