Optorite DD0401 Dual DVD Recorder - Page 14

KProbe PI/PO quality results

In the following screenshots you can see the PI/PO scans for various 4x DVD+R and DVD+RW media, recorded with the Optorite DD0401 at the maximum allowable speed.

The software used for the measurements is the KProbe v1.1.26, and the reader is the LiteOn LDW-401S. The ECC setting was 8. The specific methodology is very dependent on the drive used as a reader, and the reliability of the PI/PO provided output is also not technically confirmed. As a result, we cannot safely come up with absolute results, but we are allowed to compare the behavior of the drive with various DVD recordable/rewritable media. The official DVD specifications demand that PI should be < 280/sec (PI<<280/sec good quality) and the PO should be zero.

The discs we used came from Mitsubishi Chemicals, Verbatim, Taiyo Yuden, Ritek, Hi-Space, N-Tech and Maxell. More information about each disc type is available at the bottom of the page.
