Mobile Fidelity Sound Lab ULTRADISC 24k Gold CD-R 5-Pack in Jewel Cases

Save $10 on the Mobile Fidelity Sound Lab ULTRADISC 24k Gold CD-R 5-Pack in Jewel Cases: We Have Received Our Final Supply of the Ultimate Archival Medium, So Stock Up Now

Mobile Fidelity ULTRADISC 24k Gold CD-R is designed for professional, data critical, music and graphic archival applications, and all other data storage where there is no margin for loss or error. The best CD-Rs available, they are 99.99% pure 24k gold, tout superior scratch resistance, and are resistant to both heat and ultraviolet light. Accelerated aging tests prove ULTRADISC 24k Gold CD-Rs have a lifespan of more than 300 years. Additional features include instantaneous pit burning (burst burning) for superior pit formation and extremely low error rate plus an added, patented, scratch-resistant, protective surface. Due to these features, little if any error correction is required upon retrieval of information. Every disc comes with a limited lifetime warranty and endures a rigorous quality-control process before bearing the Mobile Fidelity Sound Lab name. We recently received our final supply of these iconic discs. Stock up today. Once these are gone, they are gone for good.

24 Karat Gold Layer and Proprietary Photosensitive Dye 
The combination of the superior reflectivity and longevity of 99.99% pure 24 Karat Gold, in addition to a specialized, patented bonding agent, ensures ULTRADISC CD-R will never oxidize and fail to output information. ULTRADISC CD-R is extremely stable in the real world environment. Unlike common CD-Rs containing Cyanine (blue/green dye) or Metal Azo (deep blue dye), which lose their characteristics quickly from exposure to light and heat, ULTRADISC CD-R utilizes a patented photosensitive dye that ensures accurate burning and stability, plus exceptional longevity and durability. The unique photosensitive dye utilized in ULTRADISC CD-R has an annular structure, which forms a strong and extremely stable chemical bond.

Extremely Accurate Burning
Mobile Fidelity Sound Lab has chosen to offer only slower speed (1-12X) CD-Rs. Through a careful battery of tests conducted at Mobile Fidelity Sound Lab, engineers observed that real-time burning has always yielded superior results. Higher burning rates cause errors and do not allow for proper pit formation. Furthermore, higher speeds cause vibration in the drive when burning the disc, thereby increasing jitter. In order to attain even higher burning accuracy and overall quality, a specially formulated dye is created for these slow-burn, precision ULTRADISC CD-Rs.

Precise Information Retrieval
ULTRADISC CD-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.

Four Levels of Quality Control
Utilizing the highest quality control standards in the industry, all the manufacturing and packaging of ULTRADISC CD-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 four-level quality control process. First, a sample out of every 3,000 discs is tested, critically examined, and evaluated for more than two hours until given the approval for MFSL specifications. Second, every single ULTRADISC CD-R is tested as it comes off the replication line. Extremely sophisticated computer analysis is used to test jitter, thickness tolerances, gold uniformity, and disc eccentricity. Then, an inspector picks up and visually examines the ULTRADISC CD-Rs for pinholes, gold consistency, oyster shelling, or any other anomalies. Finally, another inspector repeats this very time-consuming, manual/visual examination just before the specialized, stray-reflection-reducing black coating is applied. If a disc does not pass Mobile Fidelity Sound Lab’s elevated specifications, it will not be accepted as an ULTRADISC CD-R.
