C1 / C2 Error Measurements

We measured the C1 / C2 error rate on the recorded discs we burned at the maximum supported writing speed of 48X. The software we used is PleXTools Professional v2.17, and more specifically the built-in Q-Check utility. The reader was the Plextor PX-712A (firmware v1.05).

BenQ 80min 52X CD-R @ 48X

Maxell 80min 48X @ 48X

MMore 80min 52X @ 48X

TraxData 80min 52X @ 48X

TY 80min 48X @ 48X

- Summary

We should not forget that the drive writes CD media at 48X. Writing quality is expected to be reduced at this speed. Most media burned ok, while in three cases C2 errors were reported. However, in all these cases there was no error with CDSpeed.
