Mitsubishi Kagaku Media and Pioneer Introduced 100GB Archiving Recordable Blu-ray Disc and Drive

Mitsubishi Kagaku Media Co., Ltd. released an enterprise grade 100GB recordable Blu-ray Disc (BD-R) BDXL for Archive at the end of September.

It is intended for professional applications involving long-term storage for ten or more years, including digital archiving of official documents, corporate documents obliged to store and the like.

In addition, it is compliant with the guideline of the Optical Archive Group (OPARG), which is a cooperative alliance group for building a framework for optical disc archives.

Enterprise Grade BD-R BDXL 100GB for Archive can record data in optimal conditions with the support of a specialized drive, Pioneer Corp.‘s professional BD drives BDR-PR1M and BDR-PR1MA, achieving initial recording characteristics which could result in extremely long archival life.

One of the most important factors affecting long-term storage stability is initial signal characteristics. When writing at high quality using a specialized drive that matches the recording characteristics of archival discs for professional use, the recording quality is guaranteed in its initial state.

In addition, the manufacturing lines at Mitsubishi Kagaku Media’s plant are managed at standards stricter than those for ordinary products. Furthermore, strict product controls are in place for shipment from the plant, the probability of data playback defects is reduced to a minimum, and recording quality in the initial state, which greatly affects long-term storage, is guaranteed.

With Enterprise Grade BD-R BDXL 100GB for Archive, in accelerated testing using the Arrhenius method, the results for projected life showed that data could be read even after fifty years or more in storage conditions at room temperature 25°C and 50% relative humidity.

Also data will be read even if the disc temporarily comes into contact with a harsh environment, for instance; when the disc is damaged by immersion in water or saltwater (5%) or exposure to high temperatures and high humidity (80°C/80% RH), low temperatures (-40°C).

Mitsubishi Kagaku Media has accumulated over twenty years of technical know-how regarding recordable optical discs as digital storage media, starting with CD-R, and has a track record of reliability for long-term storage.

Optical discs are also media suitable for long-term storage because they do not require electricity to store, making them low in cost and in environmental burden, and because as a general rule it is not possible to tamper with recordable discs, because recordable optical discs are true write-once media. Enterprise Grade 100GB BD-R BDXL for Archive was designed as an optical disc with characteristics optimized for long-term storage.

Mitsubishi Kagaku Media will continue to develop and manufacture Enterprise Grade Discs for Archive at its own plants and will offer archival discs that meet the varied needs of our customers.
