In these tests we will be using a Lite-On SOHW-1693S drive with firmware KS0B along with KProbe to measure the disc quality. We will also be using the NEC ND-4551A with firmware 1-07 along with CD-Speed for our read-back tests.

CMCMAG.AE1

Disc Type:

DVD-R

Capacity:

4483MB

Certified Speed:

8x

Write Speed:

6x

Write Time:

14m:22s

PI-8 errors Average/Sec:

Datawrite media, with CMC media code and the results are good although the drive was not written at its certified speed.

Disc Type:

DVD-R

Capacity:

Write Time:

16m:31s

PI-8 errors Average/Sec:

37.21

PI-1 failures (PIF) Avg/Sec:

0.15

The PI slightly exceeds the limit where the disc was written at 8x and our reading device had to slow down during the transfer rate test.



Brand:

Fujifilm Labelflash

Manufacturer:

RiTEK Corporation

Code:

RITEKF1

Disc Type:

DVD-R

Capacity:

4483MB

Certified Speed:

8x

Write Time:

14m:38s

PI-8 errors Average/Sec:

185.70

PI-1 failures (PIF) Avg/Sec:

0.23

The drive often exceeds the PI limit of 280 and the reading curve was not as smooth as it should be for a good burn. Unfortunately this media is the only available Labelflash media at the moment but we cannot recommend these discs to be written with the NEC ND-7551A.



Brand:

Memorex

Manufacturer:

CMC Magnetics Corporation

Code:

CMCMAG.AF1

Disc Type:

DVD-R

Capacity:

4483MB

Write Time:

29m:18s

PI-8 errors Average/Sec:

273.40

This was a very old 4x DVD-R disc. The PI and PIF are not within the limits anymore and our reading drive also had to slow down during the transfer rate test.



Brand:

RiDisc

Manufacturer:

RiTEK Corporation

Code:

RITEKG05

Disc Type:

DVD-R

Capacity:

4483MB

Certified Speed:

6x – slowed down to 4x after writing about 3.7 GB

Write Time:

15m:29s

PI-8 errors Average/Sec:

24.63

PI-1 failures (PIF) Avg/Sec:

0.09

This disc made by RiTEK was no written at its certified speed and we would have preferred lower PI at the beginning and at the end of the disc reading back the disc should not cause problems though.



Brand:

Sky Media

Plasmon Data Limited

Code:

Plasmon1A

Disc Type:

DVD-R

15m:12s

PI-8 errors Average/Sec:

251.10

PI-1 failures (PIF) Avg/Sec:

51.18

Just like on their +R disc, we again have a very questionable result on this Plasmon disc - not recommended.

RiTEK Corporation

RITEKG05

Disc Type:

DVD-R

Capacity:

4483MB

Certified Speed:

A good result on this media manufactured by RiTEK

We have already seen much better results on this Taiyo Yuden media. You should not get any problems with these however.

A great result on this Verbatim disc and even supported at their certified speed. Highly recommended.

To sum it up: Overall, the write quality could be improved on DVD-R and is much better on DVD-RW media.
