Fujifilm DVD+RW 4x
We’ve got to rewritable media at last, and first comes a DVD+RW disc from Fujifilm. The screenshots above do not differ much, with the maximum of PI Failures being a little above the norm in both cases. The disc from the Toshiba SD-R5472 looks somewhat better, though. It has a smaller total of errors and more uniform write quality throughout the disc.
TDK DVD+RW 4x
Both drives perform worse with the rewritable medium from TDK. The maximum level of PI Failures is exceeded on both recorded discs. The errors are distributed on both discs in a similar manner.
Digitex DVD-RW 4x
Neither of the drives could produce an acceptable-quality disc in this test, too. The level of PI Failures is too high on both Digitex DVD-RW discs recorded at 4x speed. You can also see that the errors on the disc recorded by the Toshiba SD-R5472 are mostly concentrated in a single spot.
Verbatim DVD-RW 4x
The last medium to be tested, a DVD-RW disc from Verbatim, provoked no troubles with either of the drives. The errors are all within acceptable ranges. The disc recorded by the Pioneer DVR-110D is especially good: the PI Errors and PI Failures graphs are indicative of stable burn quality throughout the entire disc and of a small total number of errors.
