Ricoh MP5308D DVD±R/RW Recorder - Page 13

In the following screenshots you can see the PI/PIF scans for the DVD-R/RW media we burned with the LiteOn SOHW-832S. The software we used for all measurements is the KProbe v2.1.0, and the reader is a 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 PX-712A v1.02 using PlexTools v2.14 for comparison levels.

Comparing the KProbe/PlexTools scans we can see major differences at the reported PI/PIF error rates. The main explanation is that we have two different readers, with different pickup/chipset combination, scanning at different reading speeds (8X CAV for KProbe, 2X CLV for PlexTools). Its interesting to see the disc scanned at low & high speed, since when error rate increases at a specific disc area, it should appear at 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.

- Summary

Ricoh creates DVD-Rs with low PI/PIF error levels and offers compatibility with the majority of the media we use. Only with N-Star 4X & Vanguard 4X the writing quality isn`t acceptable with high PI/PIF error level.
