NEC ND-2500A DVD±RW recorder - Page 13

PI/PO quality results

The following screenshots show the PI/PO results for various DVD-/+R and DVD-/+RW media, recorded with the Nec ND-2500A at the maximum allowed speed.

The software used for the measurements was KProbe v1.1.28, the ECC was set to 8 and the reading drive was the LiteOn LDW-811s. The specific methodology is very dependent on the drive used as a reader, while the reliability of the PI/PO provided output is also not technically confirmed. Hence as a result, we cannot safely come up with conclusive results, although we do make a comparison of the drive's behaviour when using various DVD recordable/rewritable media.

The recording discs used came from Mitsubishi Chemicals, CMC Magnetics, Plextor, Taiyo Yuden, TDK, Ritek, Maxell and JVC. Further details about each disc are presented at the bottom of this page.

Mitshubishi Chemicals 4x DVD+RW and JVC 4x DVD-RW media were the worst performers with excessive totals and average counts for both PI and PO.

Plextor 4x DVD+R (recorded at 8x), Taiyo Yuden 4x DVD-R (recorded at 8x), Ritek 4x DVD-R media were a little better. The other brands are all acceptable with the best media being CMC Magnetics 8x DVD+R and Mitshubishi Chemicals 4x DVD-RW.
