Digitex DVD-R 8x
Now let’s switch to the DVD-R standard. The disc from Digitex passed the quality check rather successfully, having a small maximum and a low total number of PI Failures. The PI Errors graph is somewhat less stable but it still fits in the acceptable ranges described by the ECMA standards.
TDK DVD-R 16x
The reviewed drive performed well with this TDK disc, too. The errors of both types comply with the industry norms. The maximum of PI Failures is exemplarily low.
Verbatim DVD-R 16x
The quality of the “minus” blank from Verbatim is acceptable and meets the ECMA regulations. I want to note, however, that the PI Error rate and the total number of PI Errors are considerable, while the PI Failures graph shows a surprisingly low number of PI Failures.
Next go rewritable media formats. Unfortunately, I could not normally test Digitex DVD-RW 4x and Verbatim DVD-RW 4x discs recorded by the LG GSA-4167B since there was an initialization error message when I tried to start the quality check in our reference Lite-On drive (the discs, however, were quite normally read by the LG drive itself). That’s why I have to limit myself to the DVD+RW format only.
Fujifilm DVD+RW 4x
The screenshot referring to the Fujifilm disc shows a violation of the allowable maximum of PI Failures. The quality degenerates at the end of the disc, as you can see. This also refers to the PI Errors parameter, even though it complies with the ECMA standards.
TDK DVD+RW 4x
Lastly I tested a TDK disc. Unfortunately, the recorded disc does not meet the ECMA requirements as concerns the maximums of PI Failures. On the other hand, the quality of the disc is uniform throughout its entire surface.
