Sony and Panasonic have announced that they have formulated "Archival Disc", a new standard for professional-use, next-generation optical discs, in a bid to expand the market for long-term digital data storage.
Optical discs are not only dust- and water-resistant, they also can withstand changes in temperature and humidity when stored. They also allow inter-generational compatibility between different formats, ensuring that data can continue to be read even as formats evolve. Seeing the need for optical discs to accommodate much larger volumes of storage going forward, Sony and Panasonic have been engaged in the joint development of a standard for professional-use next-generation optical discs.
Both companies aim to launch systems with a recording capacity of 300GB per disc from the summer of 2015 onwards. In addition, both companies plan to leverage their respective technologies to further expand the recording capacity per disc to 500GB and 1TB.
