Recently unveiled in Tokyo, Japan, TDK’s new prototype Blu-ray Disc records data at 72 megabits per second, double the 36Mbps rate of the current Blu-ray Disc specification. The increased speed has been accomplished through recent advancements in disc recording layer formulations. The initial Blu-ray Disc standard allows for 25GB single layer Blu-ray Discs and 50GB dual layer Blu-ray Discs. To achieve 100GB capacity, the prototype Blu-ray Disc incorporates four 25GB layers. Like all Blu-ray Disc media, TDK’s prototype 100GB Blu-ray Disc is single sided.

Hideki Hirata, TDK Engineering Manager, noted, “Anticipation surrounding the release of the bare Blu-ray Disc format continues to grow. Although there’s been considerable speculation regarding next-generation Blu-ray Disc capacities, TDK is the first to successfully achieve 100GB in a working, prototype disc. TDK’s development of a prototype 100GB Blu-ray Disc with double the recording speed of the current specification validates the company’s position as a leader in extending the capabilities of optical media.”
