Writing Quality Tests - C1 / C2 Error Measurements

We measured the C1 / C2 error rate of the recorded discs we burned at the various supported writing speeds. The software we used is the PleXTools Professional v2.13, and particularly the built-in Q-Check utility. For comparison purposes, we also scanned the burned discs with Plextor Premium (firmware v1.05, 8X CLV reading speed).

Mam SGUltra 80min 48X @ 48X (PoweRec Enabled)

Maxell 80min 48X @ 48X (PoweRec Enabled)

MMore 80min 52X @ 48X (PoweRec Enabled)

TraxData 80min 52X @ 48X (PoweRec Enabled)

- Summary

Generally, we can say that the PX-712A produced good quality burns with some exceptions. The biggest problems came with Mam SG Ultra and CMC Magnetics, where C2 errors were reported. Of course, C2 errors can be corrected but a good burn shouldn't include them afterall. Comparing the drive with the Plextor Premium, we saw that the PX-712A was more "sensitive" reporting higher C1 and also C2 error rates, where the Premium didn't.
