also, regarding the comments on trying to discover a manufacturer by reading the ATIP, that is unreliable & should not be relied upon for 100%
don't trust the results from an ATIP reader unless you have some other evidence to go on
here's a quote from an advanced cdr group regarding ATIP readers that i've kept archived....
"There are two basic problems here - though the idea
is sound. First, the identification on the disc is not
definitive. What is read is at best the name written
to the master from which the stamper was made which
was then used to create the blanks. I trust that some
major manufacturers control the use of those masters
and stampers to ensure that their name does not
show up where it shouldn't, but that's not true for
all hardware or all names. So you may well read a name
there which signifies nothing.
Second, the translation from what's written into the
ATIP into the brand name is now encoded - and there's
a fee for retrieving it. That's why the programmer of
CD-R Identifier has dropped the product (though it can
still be retrieved from his site without support). Old
stampers will still translate, but that won't hold
All you can count on is that if two discs have
*different* values in the ATIP, they were not made
with the same stamper and are likely to perform
differently. If two agree, there's a chance that
they'll match, but no more than that."
