If all you're using for QC is a disc analyzer, you're missing the critical link
between process settings and disc playability » pit geometry
Disc analyzers count problems.
They can't reveal root causes.
DiscTrack Plus gives you unprecedented construction data -- precise
geometric measures of individual pit/groove features you need to locate
root
causes and correct problems.
Yes, AFM can provide these measures.
However, DiscTrack Plus provides them with unprecedented precision
and speed
-- 20X more precisely than AFM's and 144X faster.
That's why DiscTrack Plus is the perfect QC companion for disc analyzers
and
the ultimate QC upgrade for AFMs.
