Writing Quality Tests - 3T Jitter Tests

The same Nero compilation used in the previous jitter tests was used once again, this time with media from different brands. The recording speed was the maximum 40x in all cases. The following graphs show the 3T Pit & Land Jitter results.

- 3T Pit results

With all the media brands used with the Sony drive, the jitter levels were generally good. Only SKC media and to some extent Memorex, produced levels above the 35ns limit.

The average 3T Jitter values for all manufacturers discs are illustrated in the following graph.

- 3T Land results

Once again all the media brands gave low land values, with the exception of SKC media which near the end, where writing takes place on the outer tracks of the disc, we had high jitter values and Memorex media which hovered just above the limit throughout.

The average values presented below illustrates the drives recording ability.

- Summary

Generally, from this series of tests, we can conclude that the drive is a good CD recorder although, we had expected slightly better results. MAM, Imation and Creation discs gave the best results, but note that they were not recorded at full 40x.

Again we provide the link to the firmware upgrade for the Sony DRU-530A which may offer better performance here.

On the following page we check the C1 and C2 error rates for the same discs. These are the last of the quality tests.
