This sounds VERY interesting...
I have a particular interest in media longevity correlation with C1/C2 results for different brands, i.e. Do a k-probe on a newly burned disc, and then again at various time intervals out in the sun (i.e. every hour or every day or whatever). What I'm after is a confirmation of popular assumptions people make, such as: (1) the error count does increase with time, (2) it's worse for cheaper media, and (3) K-probe results will help give at least a relative feel for how long a burned disc will last
As far as media requests: (1) MAM/Mitsui is at the top of my list. We need more people to test their aggressive claims about how their gold/phalocyanine combo outlasts everyone else. (2) A couple of good-reputation brands like TY and Ricoh (3) Mitsubishi/Verbatim with the Azo dye since it's a completely different formulation from the others, and (4) Some popular cheapo brands like Princo , Prodisc, and CMC.
I'll have to admit I'm getting DVD and CD-R's a little mixed up, but whatever you do along those lines would be very interesting to see in any case.
(Oh, BTW, although I'm spewing out all this info, unfortunately I don't have a drive that can perform C1/C2 tests so all I can do is hope others will do this and post their results )
