Hot on the heels of my last thread here about Ritek BD-R causing me and a few others grief with lost data - I've got more bad news for you all.
As far as it goes - I've trusted TDK ... but it seems like they can't be trusted much longer. Specifically - the BD-R is a TDKBLD-RBA-00 and the BD-RE here is a TDKBLD-WBA-00. Both were retail bought individually wrapped in their own jewel case - both are 2x discs.
As you can see - the reflective layer is suffering rot ... and while the photos don't show it well - it has gotten dangerously close to my data. Luckily, this time, I haven't lost any data. I have other TDK's which are RBB and they seem to be all fine. See images below for the rot and the top surface of the two discs. I haven't noted any rot from any of my RITEK, CMC, Verbatim, MEIs or other TDKs (yet).
Might I suggest people might want to check their discs too? I'm in Australia so it can be counted as a fairly dry climate - one was stored in a sleeve, the other was stored in its original jewel case.
EDIT: I've just found an old CMCMAG-BA3 that has started to rot from the edge. This one was individually wrapped under the Shintaro brand. I've got at least 50 others, but they're all practically new, so they're still okay. The others are under the TDK brand in a spindle, but those ones sometimes have uneven dye coverage - looks like a little ripple radially emanating from the centre. Added the image of the dye problem to the end.
