Writing Quality Tests - Page 3

As with the Plextor drive, we used Optorite CW5201 as a burner to write the same media is all the available writing speeds. The media we used is the Memorex 48x. The jitter measurements are in the following tables.

- 3T Pit results

The 3T Pit results are good although the actual jitter value was higher than 35nsec in some cases. Writing at 20x seems to give high jitter in the beginning of the disc, reaching the 40nsec.

At the higher writing speeds the performance was also accepted although the average jitter was slightly increased. In the 52x recorded disc the jitter was higher by the end of the disc, where the writing speed reached the 52x. However, the maximum value is not very high (39nsec).

- 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 44ns, and come from the measurements on a recorded disc at 52x.

- Conclusion

Although the average 3T Pit and Land jitter values are more than 35nsec, we cannot say that the Optorite CW5201 gave a low performance. And this because it is not sure that a 39nsec jitter peak could lead to ar read error. Considering that the drive is a 52x recorder we can say that the overall performance is very good.
