TDK has unveiled a 100 GB Blu-Ray disc at a Tokyo exibition this week. TDK has achieved this higher capacity by making this a four layer disc that can record data at 72Mbps (bits per second), double the 36Mbps rate for current Blu-Ray Discs. More can be read at The Register and at Macworld
The beast holds up to 100GB of data. More to the point, it's recordable, and according to TDK, can support a write-speed double that of today's 50GB BD-Rs - or 6x (216Mbps), in other words.
The disc uses TDK's Durabis coating, announced last January, which finally allows BDs to be used without a protective cartridge, though they remain rather less resilient to scratches than DVDs.
Getting discs up to 100GB and beyond - 200GB appears to be the limit - was always part of the Blu-ray plan. TDK has talked about making 100GB BDs in the past. Alas, today's announcement, made in Japanese-language newspaper Nihon Keizai Shimbun, gives no indication as to when these discs might actually appear on the market.
