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 v2.16, and in particular the built-in Q-Check utility. The reader was the Plextor PX-712SA (firmware v1.05).

- Summary

There were C2 errors reported with certain discs that could be better. The overall writing performance of CDR media needs improvement. NEC needs to look into improving this aspect with future firmware releases. It should be noted that all discs were recorded at the maximum speed supported by the recorder.
