Memorex DVD+R 4x

DVD Identifier reports this DVD+R blank is made by CMC Magnetics Corp.

The programs scanned the disc to yield highly positive opinions about its quality. The measured maximums of PI errors and failures are noticeably below the limit, and the total number of errors is rather low, too. Like with the previous disc from Memorex, we have to admit its highest quality and recommend it to all of you.

Memorex DVD-R 4x

We’ve got two DVD-R discs from Memorex marked as rated for 4x burn speed. They should be identical in theory, but a slight difference between the paper inserts in the plastic boxes made us suspect that the discs inside were different, too. This supposition came true afterwards. The first disc proved to be a product of CMC Magnetics Corp.

The results of this test are incomplete because Nero CD-DVD Speed would freeze at about the middle of the disc. Even without that we can notice some grave problems with the quality of the recording layer. There are spikes of PI failures higher than described by the standard by a factor of ten, although the maximum of PI errors is within the norm. Judging by the overall look of the diagrams, the main problems with quality are in the middle of the disc. So, we have to reject this medium as defective. You may want to buy it only if you have no other alternative.
