PI/PO quality results

The following screenshots show the PI/PO results for various DVD-/+R and DVD-/+RW media, recorded with the Freecom drive 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 behavior when using various DVD recordable/rewritable media.

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

• Mitsubishi Kagaku 8x DVD+R (recorded at 8x)

• Mitshubishi Chemicals 4x DVD+R (recorded at 8x)

• That's 8x DVD+R (recorded at 8x)

• Philips 4x DVD+R (recorded at 8x)

• Maxell 4x DVD+R

• MCC 4x DVD-R

• MAM 4x DVD-R

• Ritek 4x DVD-R

• TY 4x DVD-R

• CMC 4x DVD-R

• MKM 4x DVD+RW

• MC 4x DVD-RW

The K-Probe test, showed that Freecom is a quality writer with the DVD+R format. All PI/PO measurements are at a very acceptable level. On the other hand, the DVD-R written media gave back high PI/PO levels while the writing quality test of the MAM DVD-R, didn't end and moreover the disc was not readable. Maybe with a firmware upgrade this issue be fixed.
