Writing Quality Tests - C1 / C2 Error Measurements

We measured the C1 / C2 error rate on the recorded discs we burned at the various supported writing speeds. The software we used is the latest PleXTools Professional , and in particular the built-in Q-Check utility. The reader was the Plextor PX-712SA (firmware v1.05).

BenQ 80min 52X @ 48X

SKC 80min 52X @ 32X

Traxdata 80min 52X @ 48X

TY 80min 48X @ 32X

Verbatim 80min 52X @ 48X

- Summary

We noticed some uncorrectable errors with certain media that should not be reported by a good burner. BenQ media, for example, reported uncorrectable errors nearly at the end of the disc, while C1 error rates were low through the whole media. TY 48X media reported C2 errors, but in all cases the discs could be read succesfully by our main DVD reader, the LiteON drive. For reference, you can see below Nero CD/DVD screenshots of the reading process.
