Phenomenal test of DVDRW media

pepst · 12.03.2026, 13:14

Dr. Gough Lui did not disappoint again and prepared what is certainly the most detailed, thorough, and laborious test of DVD RW media ever conducted. He tested the resistance of RW media to repeated rewrites, and the test yielded a few surprises.

I highly recommend reading it; it is an incredible piece of work:

A very interesting article and tests. Even though I didnt understand some of the highly technical descriptions, I found the article to be informative.
Do you know if anyone has done any similar tests on CD-RWs?

I suppose we'll see something like that in the future.

There's a second part to the test; once again, I can't imagine (or rather, I can) just how much time and effort all of this must have taken.

A fascinating collection, so far I have only read the first article, I wont have time for the second one today.
That reminded me that I have an Imation DVD-RW 4x lying around on my desk, but it looks a little different from the one in the article, and Media Type ID is OPTODISCW004. I also have an Imation DVD+RW 8x here, thats the Philips RW8-000. Ill read the next part tomorrow.

I read the second part and am a little surprised by how many new discs have degraded since then. Only two discs survived the entire cycle without any read errors. Ive seen these black spots in the recording layer before, this degradation occurred after far fewer burns than described here, and it was back when these discs were commonly sold, so they were relatively new. Its hard to say what caused it, maybe some kind of technological bug, an unfortunate combination of materials, or something like that.
