Mitsubishi-Kagaku (Verbatim) Advanced Azo dye formula patent
1 Attachment(s)
I wonder if this is the dye based used for "Advanced AZO" media, such as the 8x and 16x DVD-R and DVD+R, as well as at least one layer in the DVD+R DL blank media. Possibly even for CD-R media, based on the absorption values, although I would think it odd that a single dye (or dye base) could be used for both CD and DVD recordables. The figures clearly show (at minimum) a single- and a double-layer disc.
