Writing Quality Tests

Mitsumi DW-7801TE

We used Taiyo Yuden 80min 48x CD-R media and burned the same AudioCD project (with CD-Text) at 8x and 12x recording speeds. 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 8x 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 value reported was 29ns, and come from the measurements on a recorded disc at 16x.

- Conclusion

The average 3T Pit and Land jitter values are below the 35nsec standard for all the recording speeds. The combination of low writing speeds and the CLV writing technology seems to guarantee the quality results.
