Dye color: blue / Patented by: Taiyo Yuden
Cyanine is one of the oldest dye formulations found in recordable discs. It is chemically unstable, and somewhat sensitive to light. Cyanine discs are not usually recommended for archival purposes since they can cheimally breakdown after a few years. Many companies use proprietary additives to make the formulation more stable, and therefore improve their archival life up to 50 years. Cyanine discs will usually appear blue in color, but can appear green when coupled with a gold reflective layer. Cyanine is more tolerant of variation during the writing process, and since it is a sensitive material, is recommended for high speed recording.
The majority of blank media is produced with Cyanine. It can be the least expensive kind of disc to manufacture, and can provide excellent results for the money. The adaptation of this dye formulation by other blank media companies, such as Fuji and TDK, can yeild similar performance to other dye formulations. Although Cyanine is typically the cheapest of formulations to use, additives and other factors can make these discs just as expensive as others on the retail shelves.
- Mix CD’s
- Short-term Data Storage
- Sharing photos with friends and family
- High speed recording (Recording at greater than 32X speeds)
Dye color: clear / Patented by: Mitsui Toatsu Chemical
Since the dye is clear, these discs are usually a silver, gold, or a very light green in color, depending on the color of the reflective metal layer. Phthalocyanine formulations are extremely stable, and can have a archival life of hundreds of years, as well as top-notch performance. Phthalocyanine is a more difficult substance to write to, and is less tolerant in power of the laser during the writing process. Therefore, it is not recommended to use Phthalocyanine for high speed recording.
Phthalocyanine seems to be the second most common dye formulation used in blank media. Since the dye itself is clear, discs of these types tend to have the highest reflectivity of any blank medium. Where older drives have difficulty reading other types of blank media, these types of discs will most likely be compatible. However, the cost of quality phthalocyanine discs tend to make other dye formulations more attractive.
- Long term data storage, such as photos and documents
- Duplicating CDs
- Duplicating DVDs
- Working with older playback devices
- Holds up better in extreme conditions, like exposure to UV light
Dye Color: blue / Patented by: Verbatim & Mitsubishi Chemical
Azo is a very stable dye formulation which can last for decades. Though typically more expensive than cyanine formulations, azo discs can yeild very high performance with good durability for the money. Azo discs are usually dark blue in color.
Azo looks similar to Cyanine blank discs (given the blue color), but offers substantial performance gains. When coupled with a silver reflection layer, Azo is more reflective than Cyanine. It should be noted that although Azo is more stable over the years, additives in Cyanine can provide similar longevity to Azo. Azo is usually more expensive than a regular Cyanine disc, but advanced Cyanine formulations could be more expensive.
- Good cost for performance ratio
- Long term data storage (Under 50 years)
- Duplicating CDs
- Duplicating DVDs
Dye color: light green / Patented by: Kodak Japan Limited
Formazan is a hybrid of Cyanine and Phthalocyanine, originally developed by Kodak. The dye itself is light green, but the disc looks like a dark green when coupled with a gold metallic layer. Formazan is a rarely used formulation in the blank media industry. If available, Formazan can be an exceptional quality disc for reflectivity, write speed, and longevity. However, the cost of Formazan typically leads buyers to Phthalocyanine for their recording purposes.

Oxonol non-metallic organic
Dye Color: blue-violet / Patented by: Fujifilm Magnetics
The new Fujifilm technology is based on an organic dye that has proven to allow recording capabilities at speeds ranging from 1X to 16X. This will provide retail partners the ability to simplify shelf space by offering a recordable DVD that works with both new and legacy drives.
The new higher-speed DVDs are ideal for archiving, storage and retrieval of high-capacity data files such as photos and video. They can also be used for stand-alone PC or network backup at home or for business. Fujifilm has produced a simulated archival life estimate for the media of over 100 years (using the industry-recognized Arrhenius storage performance acceleration method.)
This environmentally friendly, heavy-metal-free organic dye was optimized for mass production by existing spin-coating manufacturing technologies.
