These DVD-R's are great.
Now, I need to clear up a misconception about DVD-R's and Sharpies.
On a DVD-R, the dye/reflective layer is sandwiched between two polycarbonate discs. It is well protected from abrasion or chemical attach. A Sharpie WILL NOT DAMAGE a DVD-R.
1)Markers have little to no effect on DVDs because the 0.6 mm thickness of the polycarbonate prevents either seepage or pressure damage. However, writing on a DVD disc that is not resting on a flat surface will physically distort the disc temporarily. Tilt is a much greater factor with DVDs because the wavelength of the ruby-red laser and the tracks are smaller than those of the infrared laser and wide tracks of the CD-R. The smaller dimensions are why the recording layer of the DVD is in the middle of the disc instead of the top (and on the bottom of the Blu-ray disc.)
2}Paper labels damage DVDs because of increases in tilt caused by the changes in tension across the label as water is absorbed and evaporated. (This can also happen when printable DVDs use ink coatings that can change over time. Most of these issues with the inks have been resolved by changes in the ink chemistry.)
3) Paper labels that are designed for CD-Rs have much less change in tilt or shrinkage on these single-piece discs. In some ways, the added cover offers some protection to the fragile upper surface of these media, but the labels must be precisely centered to avoid damage to high-speed drives trying to extract data.
4) All markers can damage CD-Rs' upper surface either by chemical interaction or by excessive writing pressure (far less likely). Water-based markers are superior, but much depends on the lacquer used. Writing on printable discs reduces the chance of damage because the coating adds another layer of protection.
I hope that clears this issue.
Cheers.
