Enterprise Grade BD-R for Archive uses Mitsubishi Kagaku Media's own Metal Ablative Layer (MABL) technology. It is one of the most stable recording layer materials due to its use of ablation to create recording marks, making it suitable for long term storage.

The label side can be given a variety of finishes depending on its intended use, including a high quality printable finish suitable for professional applications. Transmission Electron micrograph of MABL recording layer

Long-Term Storage Stability of Over 200 Years

According to evaluation results in ADTC (Archive Disc Test Center – NPO Entity), the estimated lifetime of Mitsubishi Kagaku Media’s Enterprise Grade BD-R 50GB and 100GB Archive Model has been calculated as over 200 years in 25degC/50%RH environment*1*2.

Variation in the lifetime of individual media will, in general, follow the probability distribution shown in the diagram to the lower right. In order to reduce the risk of data becoming unreadable earlier than anticipated, our Enterprise Grade BD-R for Archive is manufactured at our own company factory, and each lot is subjected to validation through accelerated aging tests. Only discs that have passed test criteria tighter than those for normal products are shipped.

Summary of Life Estimation for BD-R DL and BD-R TL

*1. We recommend the following storage environment

・Temperature: 10 to 25 degrees Celsius
・Humidity: 40% to 60% RH
・Low dust

・A fireproof, locked, condensation free storage area that does not receive direct sunlight
・Free of substances that could damage the media

*2. Test in ADTC was based on ISO/IEC16963:2011 modified for BD-R discs.

Initial Error Rate and Burst Error Count

RSER*3 (the data underlined in red in the below diagram) and burst error*4 counts (yellow dots in the below diagram) are managed to tighter criteria than those for standard products, and we guarantee recording quality in the discs' initial state due to its significant effect on long-term storage stability.

*3. Abbreviation for Random Symbol Error Rate. This is the BD error rate measured by excluding burst errors of more than 40 bytes in length.
*4. These are errors produced locally by media defects, scratches, dirt, etc.
