Writing Quality Tests - 3T Jitter Tests

On an 80min 48X CD-R disc from Taiyo Yuden we burned the same AudioCD project at 8x, 12x, 16x, 24x, 32x. The 3T Pit & Land Jitter graphs are presented here.

- 3T Pit results

As we can easily conclude from the graphs above and below, the drive gives low jitter values using 8x, 12x, 24x and 32x speeds.

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

- 3T Land results

The jitter land levels illustrated in the graph above, are very good for all speeds . Once again, recording at 16x the drive gave us really high levels.

The following average values graph confirms a good burning quality of the CyberDrive recorder, except at 16x speed.

Recording Speed	Average 3T Pit Jitter (ns)	Average 3T Land Jitter (ns)	> 35ns	Max 3T jitter values (ns)
8x	29.49	34.83	No	32 Pit, 38 Land
12X	27.17	31.63	No	31 Pit, 35 Land
16X	40	42.63	Yes	40 Pit, 43 Land
24X	31.88	32.98	No	35 Pit, 36 Land
32X	37.54	37.37	Yes	44 Pit, 42 Land

- Summary

CyberDrive is an average recorder, at least with Taiyo Yuden media. The recording quality is poor for 16x and 32x writing while is good for the other speeds. We expect that the upcoming firmware will fix this. In the following page we test the drive's writing quality with other media brands.
