Sony and Panasonic have announced a joint agreement to develop the next-generation of optical storage discs, with the proposed recording capacity of at least 300GB per disc. Their goal is to achieve this by the end of 2015. This next-gen media would be for professional-use, intended for long-term digital data storage for each companies archive business (so this is not necessarily something that could make its way into your home). Current Blu-Ray discs max out at 25GB per layer, with multiple-layer discs reaching up to 100GB capacity. I'm a fan of high density/capacity physical media because it lifts the concessions of streaming media, namely video/audio bitrate.
