Writing Quality Tests - 3T Jitter Tests

The same Nero compilation, as in the previous test, was used in order to burn 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 media, the jitter levels were once again low. Only Hi-Space and SKC media passed over the limit of 35nsec at the end.

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 Hi-Space which again, towards the end managed to go well over the limit.

The average values presented below illustrates the drives quality recording levels.

- Summary

Except for Hi-Space media, the values for the various manufacturers discs seem to be low and steady. Certainly the average values were very good, and the BTC drive seems to be on the way to establishing itself as a high quality recorder.

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