Writing Quality Tests

We used Taiyo Yuden 80min 48x CD-R media and burned the same AudioCD project (with CD-Text) at all available recording speeds ranging from 4x-12x. Below you can see the 3T Pit & Land Jitter graphs.

- 3T Pit results

As we can see from the above graphs, the 3T Pit Jitter stays below the 35ns RED book limit for all the available recording speeds. The low writing speeds, along with the implemented CLV strategy, ensure that the quality of your CD-R compilations will be high.

The average 3T Jitter values for all recording speeds are illustrated in the following table.

The 12x writing speeds gave the highest average jitter values. The average value of jitter is less than 35nsec for all the recording speeds. We could say that you can safely burn your favorite audio discs in any available speed.

- 3T Land results

The average 3T Land results are slightly increased over those in the previous measurements of the 3T Pit Jitter. The maximum jitter values reported were 30ns, and come from the measurements on a recorded disc at 4x.

- Conclusion

The average 3T Pit and Land jitter values are below the 35nsec standard for all the recording speeds. The 12x recorded discs gave some slightly increased error values, but certainly they cannot influence the overall quality. The combination of low writing speeds and the CLV writing technology seems to guarantee the quality results.
