In order to test the writing quality and readability of the burned media we
are using two readers 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-712A 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 dropoffs. 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 be taken not as the absolute criteria of the
burning quality, but as an indication level.
16X DVD+R Writing Speed
At 16X writing speed, the rotation speed and the drive's vibrations are higher
than at all other speeds. We expected to see worse results than the above,
pleasantly surprised to see such good scans at 16X writing speed. The ND-3500A
produces excellent quality discs. Quality scans indicate even better writing
than with -R media format.
