TDK is keeping busy these days with developing optical media, and it’s obvious which side of the next-gen battle they have decided to align themselves with. First, we heard the announcement of a mini BD-R capable of storing 16.5 GB of data, and now we see the manufacturer hit up the other end with the unveiling of a one-sided, six-layered Blu-ray disc that’ll stash an incredible 200 gigabytes. That’s bigger than my hard drive. Interestingly, this six-layered wonder is only four times the capacity of a regular BD-R. Either way, this is a far cry from the 4.7GB we’re used to with single-layer DVD+/-Rs.
