Read and writing performance:
For these tests we will be using several different DVD Writers to burn data to our media. We will be using CD-DVD Speed to create the test discs and for the read back tests. For the quality scanning we will use a Lite-on drive with KProbe to check the quality of the recorded media.
Before we start let us take a look at the media code:

From the screenshot above we can see that the media code is: MCC 03RG20
Now it is time to do the test burns:
Disc number 1 - BenQ DW1655:

The BenQ DW1655 used CAV (Constant Angular Velocity) to write the disc in 6 minutes and 28 seconds. SolidBurn was activated while writing this media.


PI errors are rising a little towards the end of the disc, PIF errors are low and we have a perfect read-back curve, the result is very good.
Disc number 2 - Lite-ON SHM-165P6S:

The Lite-On SHM-165P6S used CAV (Constant Angular Velocity) to write the disc in 5 minutes and 51 seconds. HyperTuning was activated while writing this media.


Once again, the result is very good.
Disc number 3 - NEC ND-4571A:

The NEC ND-4571A used CAV (Constant Angular Velocity) to write the disc in 6 minutes and 4 seconds.


PI errors are a little high, but PIF errors are low and we have a perfect read-back test; a good result.
Disc number 4 - Philips DVDR1660:

The Philips DVDR1660 used CAV (Constant Angular Velocity) to write the disc in 6 minutes and 40 seconds. SolidBurn was activated while writing this media.


PI and PIF errors are low and we have a perfect read-back curve, once again we have a very good result.
Disc number 5 - Pioneer DVR-111:

The Pioneer DVR-111 used CAV (Constant Angular Velocity) to write the disc in 5 minutes and 57 seconds.


PI and PIF errors are low on this disc and we have a perfect read-back curve; a very good result.
Disc number 6 - Plextor PX-760A:

The Plextor PX-760A used CAV (Constant Angular Velocity) to write the disc in 6 minutes and 19 seconds. AutoStrategy was set to ON.


PI errors are very low and PIF errors are also low, again the result is very good.

Sum up:
The Verbatim glossy printable media has performed very well in our writing quality tests. Every disc had a perfect read-back curve and PI and PIF errors were well within specification.
Now let us take a look at the label side of this media, and how it performs on the next page….
