Kodak is a brand which I have lots of fond memories for. They were there in the beginning of my CD-writing journey, and the brand I preferred (instead of Mitsumi, a highly respected competitor that was a little too expensive; or the cheap Chinese discs which never lasted). They helped popularize “real gold” discs (although I don’t have the full Gold Ultima in my collection any more) and mixed gold discs. Unfortunately, Kodak themselves were in financial trouble, and their media division was sold off. Products since then have been variable in quality from anecdotal reports.
Kodak Digital Science 74 minute CD-R
The earliest example I have is this CD-R which was purchased in Hong Kong back in the 4x CD-writer days. No speed is claimed on the packaging, in part, due to the recorder’s firmware determining the actual speed a user can select. This early disc has a cyanine dye on the underside, and some examples even had cut barcodes in the center. ATIP is 97m27s47f Eastman Kodak Co.
Kodak Ultima 12x 74-minute CD-R
This later disc is an example of their “mixed” gold and silver discs. I’m not sure if that means the reflective layer is silver and the dye is phthalocyanine or whether the actual reflective layer is a mix of the two metals. They did tend to last longer. As a trade-mark of Kodak’s media, there is an ID number etched into the outer rim of the media with a thick line underneath the number. This appeared to limit the overburning capabilities of the media. The ATIP is 97m27s45f with a capacity of 74m05s01f. Not particularly generous, but at least more than the claimed 74 minutes.
Kodak Ultima 12x 80-minute CD-R
At around the same time, 80 minute CD-Rs were beginning to be popularized. Unfortunately, not all recorders were compatible with the media, although a vast majority were. As a result, this particular package makes a point of advertising its 80 minute capacity quite boldly on the front. The ID code on the outer edge is retained although much more squashed. ATIP is 97m27s46f with capacity of 79m59s74f.
Kodak 4x 74 minute CD-RW
While Kodak did sell CD-RWs under its own name, these discs were not of their manufacture. The characteristics are clearly similar to Verbatim discs, and it’s no surprise the ATIP is 97m34s22f Mitsubishi Chemical Corp.
Kodak 16x DVD-R
This is from the present stage of Kodak when it became just another brand to slap onto products. This came from a bulk spindle, its MID MBI01RG40, a Moser Baer India product.
