CDSpeed/PlexTools Scans - Page 4

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

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.

8X DVD+R Writing Speed .

• Philips 8X DVD+R @ 8X

• Ricoh 8X DVD+R @ 8X

• Traxdata 8X DVD-R @ 8X

• Taiyo Yuden 8X DVD-R @ 8X

• Maxell 8X DVD-R @ 8X

• TDK 8X DVD-R @ 8X

• Verbatim(MKM) 8X DVD-R @ 8X

• CMC Magnetics 8X DVD-R @ 8X

The media would not be recognized

• BeAll 8X DVD+R @ 8X

The media would not be recognized

- Summary

According to Plextools, almost all media burned exhibited low PIE/POE rates, below the 280 limit. According to CDSpeed, all could be read successfully, without errors during the reading process. Judging from the PI/PIF scans we can say that the SOHW-1653S was very good with the exception of Verbatim media.
