In order to test the writing quality and readability of the burned media, we used two readers equipped with two software applications:
- The LiteON SOHD-167T with patched firmware being able to read DVD5 up to 16X CAV and DVD9 up to 10X CAV. For the transfer rate tests we used the latest Nero CDSpeed version.
- The Plextor PX-716A with the latest available firmware. For scanning the disc, we used the latest PlexTools version at 2X CLV reading speed, BURST mode, with middle accuracy.
In general, a "perfect" disc should have a smooth reading curve, very low PIE/POE and zero (0) POF error rates. Most times however, even though a disc has very low PIE/POE error rates, the reading curve may not be smooth containing sudden drops. Due to the fact that we oversped the reading capabilities of the LiteON SOHD-167T, such drops are expected, especially near the outer area of the disc.
The measurements below should not be taken as the absolute criterion of the burning quality, but as an indication level.
- MKM DVD+R DL 8X @ 8X
- MKM DVD-R DL 8X @ 8X
In the case of MKM+R DL media, the LiteOn drive was unable to complete the reading, as you can see from the speed graph where the second layer not read. The same disc was read by the Plextor drive but produced PO errors, including POF. In comparison, MKM-R DL media was read smoothly by CDSpeed and had acceptable values in the Plextools scans.
