KProbe/PlexTools Scans - Page 7

In the following screenshots you can see the PI/PIF scans for the DVD-R media we burned with the TDK 1616N. The software we used for all measurements is KProbe v2.4.2, and the reader is the LiteOn LDW-811S with "HS0Q patched" firmware, being able to read DVD±R/RW media up to 8X CAV. All scans have been performed at 8X with PI/PIF Sum8. Note that LiteOn drives cannot report PO but only PIF errors, despite what KProbe reports. In addition, all discs have been scanned with PX-712SA v1.05 using PlexTools v2.16 for comparison levels.

Comparing the KProbe and PlexTools scans, we can see major differences in the reported PI/PIF error rates. The main explanation is that we have two different readers, with different pickup/chipset combinations, scanning at different reading speeds (8X CAV for KProbe, 2X CLV for PlexTools). It's interesting to see the discs scanned at low & high speeds, since when the error rate increases at a specific disc area, it should appear in both scans...else it would be, perhaps, a reading glitch of the tested reader.

Note: PI/PIF errors only give us a quick look at the error rate of the burned media. Those scans should be taken not as the absolute criteria of the burning quality but as an indication level.

DVD+RW and DVD-RW Media

• CMC 4X DVD+R @ 4X

• Traxdata 4X DVD+R @ 4X

• Optodisc 4X DVD-R @ 4X

• Traxdata 4X DVD-R @ 4X

- Summary

Good quality performance was expected with DVD+RW and DVD-RW media, since the writing speed is reduced to 4X. The TDK 1616N did not disappoint us, posting again, low PI/PIF error levels.
