TDK DVD-R 8x ScratchProof

Sony DW-Q28A

Now that we have already talked about the major advantages of the ScratchProof DVD discs family in general, let’s move on to discussing their burning quality. We will start with the DVD-R discs. The diagram with the DVD disc burning quality results created for the Sony DW-Q28A drive looks impeccable. Very moderate amount of errors of both types as well as their even distribution over the surface of the disc indicate that this is an excellent medium.

In case of a different optical drive the situation changes completely. The results here suggest that this is hardly a high-quality disc, because the maximum amount of PIE and PIF errors exceeded the allowed maximum set by the ECMA standards. Although, if we take a closer look at the diagram, we will notice that these unacceptable results exist only in one single spot of the disc, while everywhere else, the error rates are within the allowed limits. In other words, it may all be not that bad in the long run.
