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 Nero CDSpeed CD Quality Test and Plextor Premium as a reader for retrieving the error rate information. The charts below illustrate the Q-Check graphs for various CD-R media.

- Summary

The results with Taiyo Yuden media are very good for all the supported writing speeds. The C1 error rate is low, and no C2 or CU errors were reported. The Memorex media had almost the same performance. With the other two media, SKC and Emtec, we tested we had low quality results especially with Emtec where the score was totally zero. In that case lot of C2 were reported.
