Dysan DVD-R 4x

The DVD-R disc from Dysan is in fact a product of CMC Magnetics.

Both programs agree that there’re no problems with the quality of the written disc. The maximums of errors are within the norm, especially the PI failures. The total of PI failures is small, too. This disc shouldn’t provoke any problems in use.

Fujifilm DVD+RW 4x

The disc selling by Fuji Magnetics is manufactured by Ricoh Co. Ltd., as you can see from the screenshot above.

The test programs agree the disc is almost perfect. We just mean the number of errors is very small, because there is no such thing as an absolutely errorless optical disc. Here, the maximums of PI errors and failures are fully compliant with the industry regulations and are even much lower than the limits. This is especially true for PI errors. The quality of the surface of the disc is uniform, too. Considering these points, the disc can be recommended for your use.
