The 7th Data Storage Expo & Conference, currently being held in Tokyo, Japan, where TDK demonstrated its four layer Blu-Ray Recordable disk (BD-R), capable of holding up to 100GB of content.
The disk features the DURABIS 2 hard-coating technology from TDK, in order to
physically protect a Blu-Ray disc's surface from scratches, dust and other factors
that could cause damage.
The Blu-ray Disc Assosiacion has not yet started the standardization procedures for
this kind of media, and according to TDK, the four-layer BD-R disc is currently a
research level prototype. TDK held a BD-R recording test, using a Pioneer BD-R/RE
prototype recorder. The TDK disc was recorded at 2x, which translates to 72Mbps
transfer rate.
Single layer (25GB) and dual layer (50GB) BD-R and BD media were also available at
the TDK booth, featuring the DURABIS 2 coating technology.
