KProbe PI/PO quality results

The following screenshots show the PI/PO scans for various DVD-/+R and DVD-/+RW media, recorded with the Artec VPP-8D24Q at the maximum permitted speed.

The software used for the measurements was KProbe v1.1.29, the ECC was set to 8 and the reading to 4X with a 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 use, came from TDK, Taiyo Yuden, CMC, Maxell , Mitsubishi Kagaku, Philips and Ritek. Further details about each disc type are presented at the bottom of this page.

• Mitsubishi Kagaku 8x DVD+R

• CMC Magnetics 8x DVD+R

• Taiyo Yuden 8x DVD+R

• Philips 8x DVD+R

• Mitsubishi Chemicals 4x DVD+R

• Maxell 4x DVD+R

• Ritek 4x DVD-R ( recorded at 2.4x)

• Maxell 4x DVD-R ( recorded at 2.4x)

• CMC Magnetics 4x DVD-R ( recorded at 2.4x)

• Mitsubishi Chemicals 4x DVD-R ( recorded at 2.4x)

• Mitsubishi Chemicals 4x DVD-RW ( recorded at 2.4x)

Unable to be read with several drives

• TDK 2x DVD-RW ( recorded at 2.4x)

Unable to be read with several drives

• Mitsubishi Chemicals 4x DVD+RW

• Maxell 4x DVD+RW

The DVD-RW media was not playable with LiteOn players, so we couldn't measure the writing quality for this type of format. Strangely, the media could not be played in other drives either, from different manufacturers.

In most cases, the PO level was very low except for Ritek 4x -R and Mitsubishi Chemicals 4x +RW media. Furthermore, Mitsubishi Chemicals 4x +RW and Maxell 4x +RW media produced unrecovered read errors. The PI levels were also in the main at acceptable levels. In general, the DVD writing quality of the drive is satisfactory.
