At last we see LG’s drives use P-CAV! It’s nice the new model, unlike the earlier ones, uses this algorithm rather than CAV for 16x burning because it brings in a real time gain. The time gain over 12x speed is small, but quite noticeable. There were no evident slowdowns during the burn session. The drive also easily read the burned disc.
As for the quality of the disc, it is high: the PI error rate is higher than at 12x, but it’s expectable considering the employed burn algorithm. Then, the total of PI errors is rather small, so I have no serious complaints about the quality.
The asymmetry has worsened if compared with 12x burning, but its fluctuations fit within the acceptable range. The jitter rate follows suit, fluctuating widely on the second half of the medium. Yet if you look at the results of TA Test, the drive quite successfully maintains the required pit/land lengths even at the maximum burn speed. There are minor overlaps at 3T-5T, but they don’t affect the quality of the disc much. Again, the overall quality is good here.
