Somewhere early January, I bought some Plextor Yuden T03 DVD+R spindels from SVP, to replace 2 spindels I bought from Germany, same Plextors, which had horrible scan results (it was suggested here it was probably hot truck syndrome).
But these new spindels also had rather disappointing scan results (>100K PIE, 3000 or more PIF, not what you’d expect with TY on a Pio 109), although most people here thought they were still OK. I never used them anyway but did take the advise to burn a few and store them to look if they decayed.
I just bought a faster scanner than my Plextor 716, a LiteON, and to test it I used one of these discs. To verify the results vs the Plextor scans, I redid that scan as well. The result was rather unnerving, a 20% error increase as you can see from the scans below. That’s way above the variation between 2 consecutive scans, so it must be real error increase.
Looks like these will not hold for the long term. Comments?
