Writing Quality Tests - 3T Jitter Tests

On an 80min 48X CD-R disc from Taiyo Yuden we burned the same AudioCD project at 40x, 48x and 52x. The 3T Pit & Land Jitter graphs are presented here.

- 3T Pit results

Looking at the graph above, we can conclude that generally the LiteOn drive performed well. After the 70th minute the drive marginallyt slopped the limit of 35ns at all speeds except for 40x, where it reached a very good high level at around 30ns. Of course, this could not affect writing quality.

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

The average Pit jitter for all recording speeds are very satisfying.

- 3T Land results

Again for 40x the performance is good. 48x can also be considered good even though it oversteps the mark with 37ns. At 52x, the Land jitter performance is good but it reached the high level of 43ns. Keep in mind that this happened only at the 80th minute.

The following graph indicates the good average performance at higher recording speeds.

- Summary

With the LiteOn SOHC-5232K, the average results were very good for both Pit and Land. We can not avoid though the significant high levels reached at the last minutes of the disk for 48x and 52x speeds. Unfortunately this is the case for most drives, so do not be misled by the high jitters at the 80th minute.

The following page where we check the jitter levels produced on various manufacturers discs, will give you a better indication of the writing quality level of the drive.
