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 PleXTools Professional v2.17, and in particular the built-in Q-Check utility. The reader was the Plextor PX-712A (firmware v1.05).

Creation 80min 48X @ 32X

MMore 80min 52X @ 48X

SKC 80min 52X @ 32X

Traxdata 80min 52X @ 48X

TY 80min 48X @ 32X

Waitec 80min 52X @ 24X

- Summary

There are several problems with some discs. The higher the writing speed, the worse the results we obtained. Worst results came with SKC 52X media. MMore media, which was the media that could be written faster than all the others, reported uncorrectable errors. Even Waitec media that was recorded at 24X reported some C2 errors. The overall writing performance of CDR media needs improvement.
