Freecom FX-50 DVD+/-RW 16X Burner - Page 9

Writing Quality Tests - 3T Jitter Tests

On this page we present the 3T Pit & Land Jitter graphs when using various media burned at 24X, 32X and 48X writing speeds.

- 3T Pit results

The highest 3T Pit jitter reached was 55nsec (Creation CD-R media), which is way above the Red Book limit of 35nsec. Best results were achieved with Waitec CD-R media burnt at 24X. Generally, the performance of the FX-50 burner was not good.

- 3T Land results

The 3T Land results were also high, reaching a maximum of 55nsec, like before. Best results came with TY media but this disc was burnt at 32X and not at 48X high speed.

It should be noted that the TDK 1616N and NEC ND-3500A drives reported similar results. Freecom should improve CDR writing quality with future firmware releases. Of course, it is always more safe to write at lower speeds than the maximum supported speed.
