Mitsui archival gold discs (marked as "Prostudio" in Europe) are designed to be
burned at lower (1-12x) speeds, whereas the "non-archival" equivalents are
apparently optimised for higher burn speeds. Not sure of any other
So if that is the
only difference....then what's makes the Gold disk markedly better (archival)
than non-archival? Or is there no real big difference regarding the
longevity, stability etc?
