Plextor PX-716A Burner - Page 18

PlexTools Scans - Page 5

In order to test the writing quality and readability of the burned media, we used two readers in combination with two software packages:

• 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, even when a disc has very low PIE/POE error rates, the reading curve may not be smooth with 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

• TDK 16X DVD-R @ 16X

• Taiyo Yuden 8X DVD-R @ 16X

- Summary

The writing quality at 16X for the minus format needs some improvement. The Taiyo Yuden media, which is certified for 8X, reported reading errors in both CDSpeed and Plextools. TDK however, which is a certified 16X media, performed well.
