Writing Quality Tests - 3T Jitter Tests

The Philips DVDRW885K supports a maximum writing speed of 24x and uses P-CAV writing strategy for the writing tasks. Since this supported writing speed could be considered as a safe writing speed, we expect to see quality results.

- 3T Pit results

The CD recording quality for the Philips drive, according to our measurements, is very good in all cases except with Traxdata media which revealed the highest jitter values among all media. The average levels are lower than the 35ns RedBook limit, except for Traxdata which is only a little higher. The average values are given below.

- 3T Land results

As with the Jitter Pit levels, we come to the same conclusions with the Jitter Land values, with Traxdata media displaying the highest readings.

Recording Speed	Average 3T Pit Jitter (ns)	Average 3T Land Jitter (ns)	> 35ns	Max 3T jitter values (ns)
Traxdata 52X	35.71	37.80	Yes	38 Pit, 42 Land
MMore 52X	30.12	31.10	Yes	33 Pit, 36 Land
