Writing Quality Tests - 3T Jitter Tests

In order to test the writing quality of the written discs with Memorex True-8x we summarize the 3T Pit & Land Jitter of the written discs in the following graphs.

- 3T Pit results

Memorex proved to be a qualitative writer on all tested CD-R media. None of the discs exceeded the 35ns Red Book limitation, as it shown on the above graph. The highest Pit value (32ns) comes from the Ritek media at the beginning of its surface while the most stable measurements were indicated with the Fuji media.

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

On the above graph the average Pit Jitter of each media is presented. Memorex and TY media returned the highest average values but these values are lower than the 35ns Red Book limitation. This means that the specific media can safely be used for quality writing. On the other hand MAM and Fuji gave back low average Pit Jitter, 23.05 and 23.98 respectively.

- 3T Land results

Just like the previous Pit values measurements, the Ritek disc gave back the highest Land Jitter value, 35ns, while the Fuji disc gave the most stable measurements. None of the written discs exceeded the 35ns Red Book limitation.

The following average graph confirms the low levels.

The average Land Jitter values for all written discs were good. The highest average values were indicated with Memorex, written at 24x, while the lowest comes from Fuji.
