51GB disc, the Blu-ray side has a new creature of its own to talk about. Co-developed by Pioneer and Mitsubishi, the LTH (Low to High) BD-R reportedly utilizes an "organic dye recording layer," and is said to be a recognized format within the Blu-ray Disc Recordable Format v1.2 standard. Additionally, the two companies boast that this disc won't require "large-scale plant investments" to manufacture, which is music to the ears of anyone who enjoys lower costs. Regrettably, it sounds like existing Blu-ray drives won't play nice with the LTH BD-Rs as-is, but here's to hoping that firmware updates could fix that.
