ULTRADISC DVD-R – The Ultimate Archival Media
The 24 Karat Gold ULTRADISC™ DVD-R is designed for professional, data critical, music and graphic archival applications, and all other data storage where there is no room for loss or error. These specially gold plated ULTRADISC™ DVD-R’s ensure excellent reflectivity, no corrosion, and dramatically improved resistance to light and heat. Additional features include instantaneous pit burning (burst burning) for superior pit formation and extremely low to no error rate; and an added, patented, scratch resistant, protective surface. Due to these features, little if any error correction is required upon retrieval of information, producing precise reproduction of stored data. The average DVD-R has a projected lifespan of 20 years—if stored in ideal conditions. Accelerated aging tests show that the ULTRADISC™ DVD-R retains its specifications for more than 100 years. Now information can be accurately stored and retrieved virtually forever.
24 Karat Gold Layer
Mobile Fidelity Sound Lab created the world’s first 24 Karat Gold music CD in 1987, the ULTRADISC™. Now MFSL has put that expertise into the development of the ULTRADISC™ DVD-R. The combination of the superior reflectivity and longevity of 99.99% pure 24 Karat Gold, plus a specialized, patented bonding agent, ensures that the ULTRADISC™ DVD-R will never oxidize and fail to output information, as many commercially available DVD-R’s do. The ULTRADISC™ DVD-R is extremely stable in the real world environment.
The ULTRADISC™ DVD-R utilizes a state-of-the-art scratch and chemical resistant coating that provides unprecedented protection. This extremely resilient material is impervious to chemicals and 7 times more scratch resistant than an uncoated disc. DATAGUARD treated discs greatly reduce the possibility of uncorrectable errors. If a disc is accidentally mis-handled DATAGUARD will lower error correction during playback, therefore improving read accuracy.
Proprietary Photosensitive Dye
Unlike commonly used DVD-R’s containing Cyanine or Azo, which can lose their characteristics quickly from exposure to light and heat, the ULTRADISC™ DVD-R utilizes a patented photosensitive dye which ensures accurate burning and stability, plus exceptional longevity and durability. Whereas the two other types of dye are formed with linear molecular structures, which break down easily when exposed to the elements, the unique photosensitive dye utilized in the ULTRADISC™ DVD-R has an annular structure which forms a strong and stable chemical bond.
Extremely Accurate and Precise Burning
When recording speeds are increased three major problems occur. Parity of inner-code (PI) errors rise as a result of an increase of laser burning power which leads to pitch (pit?) deformation. As burning speeds rise so does signal jitter due to thermal interference. Furthermore, higher speeds cause vibration in the drive when burning the disc, increasing mechanical jitter. MFSL engineers urge professionals to burn their data in
real time, better known as 1X for the most accurate results.
Accurate and Precise Information Retrieval
The ULTRADISC™ DVD-R’s specialized dye reacts more quickly to the writing laser than do other dyes. It reacts in a "burst" mode instead of the sluggish "melt" mode. Due to this instantaneous reaction, precise pit edges are formed. This is crucial for the laser pickup to
accurately interpret the information, and thereby reducing or eliminating the use of interpolation/error correction circuitry. Additionally, a specially formulated, black ink is used to coat one side of the disc in order to reduce stray reflections which could alter readings.
Ultra Quality Control - 4 Levels of QC
Utilizing the highest quality control standards in the industry, all the manufacturing and packaging of the ULTRADISC™ DVD-R is done in
state-of-the-art cleanroom conditions. Mobile Fidelity Sound Lab has rejected random sampling techniques, which are simply not stringent enough for critical data storage applications. Instead, MFSL utilizes
an unprecedented 4-level quality control process.
First, a sample out of every 3,000 discs is tested, critically examined and evaluated for over 2 hours until given the approval for MFSL specifications.
Second, every single ULTRADISC™ DVD-R is tested as it comes off the replication line. High tech, extremely sophisticated computer analysis is used to test jitter, thickness tolerances, gold uniformity and disc eccentricity.
Third, an inspector (wearing gloves) picks up and visually examines the ULTRADISC™ DVD-R’s for pinholes, gold consistency, oyster
shelling, or any other anomalies.
Fourth, another inspector repeats this very time-consuming, manual/visual examination just before the specialized, stray-reflection-reducing black coating is applied.
ULTRADISC™ DVD-R’s have to pass all levels of QC before they can be shipped. If a disc does not pass Mobile Fidelity Sound Lab’s elevated specifications, it will not be accepted as an ULTRADISC™ DVD-R. This is MFSL’s guarantee to the user that every ULTRADISC™ DVD-R is the finest engineered recordable media available.
After creating a DVD-R that would last a lifetime, MFSL backs it up with a limited lifetime guarantee.
