KProbe PI/PO quality results

The following screenshots show the PI/PO scans for various DVD-/+R and DVD-/+RW media, recorded with Aopen dual 8x8 at the maximum permitted speed.

The software used for the measurements was KProbe v1.1.28, the ECC was set to 8 and the reader was LiteOn LDW-811s. The specific methodology is very dependent on the drive used as a reader, while the reliability of the PI/PO provided output is also not technically confirmed. Hence, we cannot safely come up with conclusive results, although we do make a comparison of the drive behavior when using various DVD recordable/rewritable media.

The recordable discs we used, came from Verbatim, Taiyo Yuden, CMC, MAM, Maxell , MC and Ritek. Further details about each disc type are presented at the bottom of this page.

Kprobe awards the Aopen drive with quality results. From the screenshots above we can see that all media used for the quality measurement, returned good PI/PO levels. However the values are slightly increased at the end of each disc but still acceptable for both DVD+R and DVD-R formats, even from media that are certified for slower speed writing.
