Hi all!
Im new to this forum, and i found this topic on google. Well i realize that this thread is somewhat old, but anyway i just want to show you some "aging examples" about these TDK003 discs.
Well i experimented with them a lot, because some of these discs were mostly unreadable, so here's what i found out:
-only the DVD+R 5727C2 (wich text is in the inner plastic ring of the disc) discs are affected by this degrading effect
-in front of this code, there is another. I have found three different: M0906, M0901 and M0723.
Well the first is the worst, these M0906 dvd-s are now mostly unreadable/unrecognizable by any drive (at first, the LG-GSA H44N recognized them, but with many CRC read errors and painful slowdowns

).
The M0901 discs are fully readable, although some of them had CRC errors on a Pioneer DVR-109, but the LG could cope with that. Same for the M0723, they are readable and at least all of them produce very bad quality scans
So here are the scans, made with a Samsung SH-S203D drive, i dont know how reliable its quality scan results, but i think they're far more believable than the scans made by the Pioneer DVR-109...

The first test is about a M0906 disc (somehow i found a few of these discs that are still recognizable), the second is M0901.. maybe later i'll do a scan with the M0723 too.
