Sony and Panasonic have joined forces to launch the successor to Blu-ray which they hope will grow the market for long-term, optical storage.
The launch of Archival Disc is the result of the manufacturers’ partnership to develop a standard for professional-use optical discs, which was announced in July last year.
Both firms now plan to launch systems with a recording capacity of 300GB per disc from summer 2015.
They also want to expand the recording capacity per disc to 1TB.
