LG GSA-4120B DL Recorder - Page 13
KProbe/PlexTools Scans - Page 3
In the following screenshots you can see the PI/PIF scans for the DVD-R media
we burned with the LG GSA-4120B. The software we used for all measurements
is KProbe v2.2.2, 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 PIF errors, despite what KProbe reports. In addition, all discs have been
scanned with the PX-712SA v1.03 using PlexTools v2.15 for comparison levels.
Comparing the KProbe/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 disc
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.
12X DVD+R Writing Speed
- Taiyo Yuden 8X DVD+R @ 12X
The recording quality is outstanding for the 12X writing speed. The best results
came with Maxell and TY 8X media with very low error rates from both KProbe
and Plextools software. Excellent performance!
