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, and 16x. The 3T Pit & Land Jitter graphs are presented here.

- 3T Pit results

The measurements we took from our machine revealed the great CD recording quality of the drive. The values are far below the Red Book Limit of 35nsec.

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

As you can see the average measurements are very low, which means better writing quality at all speeds.

- 3T Land results

As with pit jitter, land jitter values are also quite low and below the Red Book limit of 35nsec.

And just to confirm it, the average jitter for all speeds presented in the graph below show just how low the values for land jitter were.

- Summary

Philips JR4DVDRW had very low jitter values in both Pit and Land. The drive shows an ability to burn discs at maximum speed and high quality.

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.
