CDSpeed/PlexTools Scans - Page 1

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 overspeed 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.

CMC 16X DVD+R @ 16X

Verbatim 16X DVD+R @ 16X

- Summary

Although no POF errors were introduced and all media burned at 16X was readable, high PI error levels were reported. According to the graphs above, Memorex needs to improve its writing quality at 16X speed.
