Writing Quality Tests

Plextor PX-504A

As in the previous test, we used Taiyo Yuden 80min 48x CD-R media and burned the same AudioCD project at all available recording speeds. Below you can see the 3T Pit & Land Jitter graphs.

- 3T Pit results

The 3T Pit Jitter values are very low for throughout the disc.

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. Such jitter values definitely cannot influence the quality of your writing compilations.

- 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 28ns, and come from the measurements on a recorded disc at 8x.

- Conclusion

The average 3T Pit and Land jitter values are below the 35nsec standard for all the recording speeds. As with the Mitsumi model, the writing quality of Plextor PX-504A is high.
