CDSpeed/PlexTools Scans - Page 7

In order to test the writing quality and readability of the burned media we used 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.

DVD+RW and DVD-RW media format

• Verbatim 4X DVD+RW @ 4X

• Optodisc 4X DVD+RW @ 4X

• Traxdata 4X DVD+RW @ 4X

• Verbatim 4X DVD-RW @ 4X

- Summary

The recording quality with most 4X +R media was very good. It should be noted, however, that some 4X -RW media (Traxdata -RW media for example) could only be recorded at 2X.
