Writing Quality Tests

We used 80min 48x CD-R media by Taiyo Yuden and burned the same AudioCD project at 4x, 8x, 12x and 16x. In the following page you can see the 3T Pit & Land Jitter graphs.

- 3T Pit results

In general, the drive did not introduce high values of 3T pit jitter in the specific media. The highest 3T pit jitter was reported on the discs recorded at 16x, but the values were very low.

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

- 3T Land results

The average 3T Land results are slightly increased over those in the previous measurements of the 3T Pit Jitter. However, the results are very good since the jitter was kept lower than 28msec for all the discs.

- Conclusion

The average 3T Pit and Land jitter values are below the 35nsec standard for all the recording speeds. The CLV writing strategy which is being followed in all the writing speeds, along with the (relatively) low supported speeds, help this drive maintain low jitter values and allow us to expect a high writing quality.

- C1 / C2 measurements

We used Plextor Premium and the latest version of PlexTools Professional software to measure C1 / C2 error rate on the the recorded discs of Pioneer DVR-A06.

• Taiyo Yuden 48X @ 16x

• Taiyo Yuden 48X @ 8x

The measurements reported no CU (uncorrectable) errors on any of the discs. The 16x recorded disc gave some C2 errors around the 55:00:00 address of the disc (blue peak), but the overall quality is still high.
