3T Land Results

The best results come from the 4X normal recording speed. Again the +2 setting won't produce very well results.

The lowest 3T Land Jitter comes from the 4X normal speed. The two extreme values (+2, -2) will give also extreme results, but of course Plextor also suggests to avoid them.

- Conclusion

Mode	Recording Mode	3T Pit Jitter	>35ns	Max value
VariREC	-2	28.10	No	29
	-1	27.05		28
	+0	26.44		28
	+1	28.20		30
	+2	31.37		32
Normal (DAO)	4X	26.22		28

Mode	Recording Mode	3T Land Jitter	>35ns	Max value
VariREC	-2	33.61	Yes at 4mins	36
	-1	32.07	No	34
	+0	32.10	No	34
	+1	32.39	No	34
	+2	33.85	Yes at 0mins	36
Normal (DAO)	4X	30.90	No	34

As we had seen with the RITEK JS type media, VariREC won't improve the 3T Jitter compared with the normal 4X recording (DAO) speed. In case of using the extreme values (+2, -2) the disc will exceed the 35ns limit!
