TDK's 100GB Blu-ray Disc

Much of the talk between Sony and Toshiba about exchanging numbers, going on a date and having that nervous first kiss appears to have died off and we’re back to the more traditional format fighting that accompanies new technologies. Blu-ray partners look determined to rub HD DVD’s nose in it too as TDK has now announced a 100GB Blu-ray disc.

The four layer behemoth is recordable and, according to TDK, capable of writing data at 72Mbps - double that of current Blu-ray media. It also rather rains on the parade of the 45GB triple layer HD DVD disc only announced this month.



Adding to the Blu-ray foot stamping is the news that the disc uses TDK’s own Durabis hard coating (illustrated above), something that removes the need for the media to be contained within a protective casing (a previously severe limitation, but one always likely to be fixed before public release).

Given that Blu-ray is not even on the market yet, it is remarkable how quickly the media capacity is being scaled up. Eight layers or up to 200GB per disc is the theoretical maximum of Blu-ray and at this rate we may see a company demonstrate such a thing sooner rather than later.

In reaching these sizes, Blu-ray is clearly moving beyond its primary role as a movie disc and making a beeline for the back-up storage market. That said, with a single layer 25GB Blu-ray disc supposedly capable of holding 135 minutes of high definition video, the Lord of the Rings Trilogy: Extended Edition still remains a long way out of reach!
