Without any troubles, slumps or variations of speed, the drives successfully completed the burning and reading of the discs. The new model again boasts better results than the GSA-4160. The total number of PI errors has diminished from 35,456 to 21,498 with the new drive, and I’d call it a big difference. The total of PI failures is higher on the disc from the GSA-4163, though. On the other hand, this high total comes mostly from the two small-length spikes of PI failures, which don’t affect the overall quality of the medium much. Thus, the GSA-4163 again improves on the results of its predecessor.

Beta/Jitter and TA Test (Inner, Middle, Outer)
for the disc burned by the LG GSA-4163B
 
 

The asymmetry is normal, its fluctuations are small. The jitter rate is low and keeps on about the same level through the entire disc. The results of TA Test also agree that we have an excellent quality of burning here!
