TDK DVD+R 16x

This DVD+R disc rated for the maximum burn speed of today, 16x, is both manufactured and marketed by TDK Corp.

The diagrams with the test results say the quality is normal. The total number of errors is small, while their peaks are much lower than specified by the industry standards. The overall look of the diagrams indicates that the recording layer of the disc is stable enough. Considering this performance, the disc can be recommended to all users who need the fastest write-once media.

TDK DVD+R 8x

This DVD+R disc with a maximum burn speed of 4x is manufactured by Ricoh Co. Ltd.

There’s difference between the two diagrams with the results of the test. Nero CD-DVD Speed says the maximum of PI failures is two, while KProbe says six. The difference seems big, but if you take a closer look at the diagrams you may note only the first value, i.e. two failures, in both of them. The peak of six PI failures was evidently registered as a single spike which is not displayed on the diagram according to the selected “Remove the spike” option in the program’s options. Such a spike doesn’t affect the overall quality of the disc much.

The total number of errors is rather small, but there’s an increase of them towards the end of the disc. Note also that the maximum peaks of PI errors are, too, much lower than the limit set by the standards. On the whole, this medium seems a good product, worthy of your consideration.
