Sony and Panasonic announced last year that they had plans to develop a new, high-capacity optical storage disc -- and they weren't lying. New details indicate that a new Archival Disc format will have a capacity of up to 1TB.
Claiming that the Archival Disc format will be hardy -- coping well with dust, temperature and humidity -- Sony and Panasonic plan to endow the format with "inter-generational compatibility". That means that while the first iteration, due summer 2015, will cram 300GB onto a single disc, the associated kit should play nicely by the time a 1TB disc arrives... some time.
Primarily be targeted at "professionals", these high-capacity discs should be good for backups and archiving -- especially when it comes to HD video and the like. Who needs Blu-ray anyway? [Sony via Engadget]
