Writing Quality Tests - 3T Jitter Tests

On an 80min 48X CD-R disc from Taiyo Yuden we burned the same AudioCD project at 8x, 16x, 24x, 32x and 40x. The 3T Pit & Land Jitter graphs are presented here.

- 3T Pit results

As we can easily conclude, from the given picture above, the BTC drive performed extremely well, keeping the jitter values at a low, and certainly well within the Red Book level. No matter what the speed, the drive reported good quality results. The 8x recording speed was the best while all the others were also rather good, especially 40x.

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

Here it can be clearly seen that the pit jitter levels were very low.

- 3T Land results

As with pit jitter, land jitter values were also low and below the Red Book limit of 35nsec. All the speed had quality results.

The following average graph confirms the low levels.

- Summary

The BTC DRW1008IM has proved to be a high quality CD recorder, regardless of recording speed.

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