What many consumers don't understand is that there are only a few CDR
manufacturers and they OEM the discs to other companies for them to
sell under their brand names (Like FujiFilm, Memorex, Kingston etc).
Often, these companies will change who they get the CDR's from and
sometimes they use multiple manufacturers at the same time so you
never know what you're getting.
CDR Identifier is your
best bet to finding out who actually MADE the CDR's and what the dye
type used is. (Which may help you identify discs that will work in
your particular application)
