Having recently purchased a DVD burner and having had a CD burner for
some time, it occured to me that there may or may not be differences in
blank media, such as there are in blank analog tape.

Is there any research that indicates any qualitative differences in
blank CD or DVD media?

Having searched Google already, I was unable to find any sort of
definitive tests on the subject, indeed it seems that it is not
something that any particular attention has been paid.

Yes. You are ill-informed, igorant, and suffer from general mental
mediocrity. However, I'll try to explain to you what your inadequate
Googling skills could not pick up.


That from RAO's reverse barometer, and one of the least informed people
in the world on real audio differences.

There is a spec called "block error rate", BLER. All optical media have
numerous errors of manufacture, which are normally hidden by the fact that
the data is recorded using error correcting codes. However, the number of
errors per block differs between brands, grades, and types.

However, the higher the BLER, the higher the probability the media will fail
in use, ie. fail to be read on some device.

The BLER is the primary metric for differentiating quality levels of optical
media.

Time will tell, so far none of the medi I've used have had any problem
other than the one TDK disk I mentioned.
