DigiTimes is reporting on Pioneer’s new layered optical disc. Each of the disc’s 16 layers holds 25GB, for a total storage capacity of 400GB. That’s 8x the storage on a double-layer Blu-Ray disc, which according to my CrunchGear companions holds an awful lot of porn. The new discs use a reflective layer, but should be compatible in existing Blu-Ray players, according to Pioneer.
