Writing Quality Tests - C1 / C2 Error Measurements

The C1 / C2 error rate was measured for the recorded discs burned during the previous writing tests (jitter). The software used was UMDoctor Pro II, and the reader the Optorite DD0203 drive.

- Summary

In the main, these are very good results. The C1 levels are rather low, with the exception of Creation media. C2 errors were reported with Creation and more pronounced with Hi-Space media. In the case of Creation media, the C2 errror levels appear to be located in the same region on the disc which produced the high jitter values in our previous tests. Other than this, the remaining results were very good.
