Does any know who makes the 90 and 99 min cdr from allmediaoutlet.com (unbranded silver/silver) ?
Most likely they are made by Plasmon 97 27 18

The Ciba's 2nd dye, Super Green, generated a huge process window for the CDR manufacturers,
which means that they could easily produce good CDRs.
The only problem was that the dye was rather expensive.
The Ciba's 3rd dye, Ultra Green, is still better and most importantly relatively cheap.
This made many manufacturers to go over to the usage of the Ciba's dyes.
...as world wide demand for CD-R media soared and the Plasmon- Ciba â€˜Super Greenâ€™ dye established itself as the leading phthalocyanine process technology with the Far Eastern disc manufacturers. In the coming year we will launch our new â€˜Ultra Greenâ€™ high-speed dye that will improve the cost competitiveness of the production process and enable us to exploit the continuing rapid growth of the CD-R market.
New dye compositions had been introduced, notably CIBA's Super Green for easier laboratory handling, and these gave the opportunity to reduce cycle times and provide easier process adjustment at the machine.
Super Green dye required stampers with a groove depth of approximately 200 nanometres and Emould had modified screw geometry to provide suitable melt characteristics for the precise reproduction of these profiles.
