Electronics giants Sony and Panasonic are to collaborate on the development of the next-generation standard for professional-use optical discs as they expand their respective archiving technology businesses. The two companies hope to create an optical disc with a reported minimum capacity of 300GB by the end of 2015.

Both Sony and Panasonic already offer large-storage optical discs but current solutions only accommodate a system of multiple discs, each with a maximum storage capacity of 100GB. They claim there is an increasing demand for large-storage optical discs from traditional video broadcasters but also from cloud service providers.

Sony and Panasonic's 300GB disc, like a number of high capacity optical discs already commercially available, is destined for the data storage and archiving rather than the consumer market. The largest capacity optical discs for consumer applications are Blu-ray Discs (BD) and their size echo those used for pre-recorded filmed entertainment at typically either 25GB or 50GB, single and dual layer discs respectively.

For commercial storage applications, BD also represents the largest capacity recordable optical discs currently available. The BD standards BR-R 3.0 and BDXL formats provide 100GB and 128GB write-once discs, three and four layer BDs respectively. In addition to these the standard for a 100GB rewritable disc BDXL format disc for commercial applications was also released in June 2010.                                                                   

This recent example of collaboration between Sony and Panasonic follows ongoing joint research to commercialise OLED TV technology announced mid 2012.
