Writing Quality Tests - 3T Jitter Tests

The TEAC DV-W58G supports 40x maximum writing speed. We burned five TY discs to test the quality at all available writing speeds and five media from other manufactures to test the writing quality with various media.On the following graphs we summarize the 3T Pit & Land Jitter of the various written discs.

- 3T Pit results

The Pit Jitter results for the TEAC drive are higher than we had expected. Apart from CMC, Ritek and MAM media, the rest returned higher pit values than the 35ns Red Book limit. Notice on the above graph that the TY disc returned the highest results. Also note that the MAM disc was written at 24x although it is certified for 48x maximum writing speed. In addition both MAM and Ritek discs, gave back Time Outs (non readable areas) during the measurements.

The above graph shows the average Pit values for each recorded disc. Notice that even the average Pit for the TY disc, exceed the 35ns Red Book limit.

- 3T Land results

The Land Jitter values for the same discs written with the TEAC DV-W58G are at around the same levels in comparison with the Pit values. CMC is the only media brand that remained within limits in both land and pit jitter.

The following average graph confirms the low levels.

The above table shows that apart from CMC media, all other media returned final values over the 35ns Red Book limit, although having a closer look at the table we can also see that only TY and TDK media returned average Pit and Land values higher than the 35ns Red Book limit.
