Writing quality Tests

The following screenshots present the PI/PO results for various DVD-/+R and DVD-/+RW media, recorded with LiteOn LVW-5005 at the maximum allowed speed. Before the tests we flash the device with the latest available firmware by LiteOn.

The software used for the measurements was KProbe v2.1.0 for the minus format and v1.1.29 for the plus format since the newest version had some problems and couldn't locate the disc size. The ECC was set to 8 and the reading drive was LiteOn LDW-811S. The specific methodology is very dependable on the drive used as a reader, while the reliability of the PI/PO provided output is not also technically confirmed. Consequently, we could not safely come up with any conclusive results, but still, we did make a comparison of the drive's behavior when using various DVD recordable/rewritable media.

For the CDSpeed reading tests we used SD-1712 DVD-ROM from Toshiba.

CMC Magnetics 2.4X DVD+R

Generally the drive offers good writing quality. However there were instances of increased PI/PO levels, which fortunately didn't affect the reading procedure.
