TDK has developed a prototype recordable Blu-ray Disc with revolutionary 100GB capacity. By far the most advanced optical media ever developed, the prototype 100GB bare Blu-ray Disc doubles both the capacity and recording speed of the current Blu-ray Disc specification. Blu-ray’s industry-leading capacity means a single disc can store a vast assortment of content without making quality compromises. A single, prototype 100GB Blu-ray Disc can store approximately 9 hours (Recorded at 24Mbps) of high definition video.
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.
Because Blu-ray Disc media’s data tracks are quite narrow even in comparison with DVD media, precise, stable interaction between the laser and the recording material is especially critical to ensuring error-free recording and playback. That’s why TDK developed DURABIS, an innovative hard coating technology that makes bare Blu-ray Disc media a reality by protecting the disc surface against common contaminants such as scratches, fingerprints and dust adherence.
DURABIS increases the scratch resistance of Blu-ray Disc media by a factor of 100, as demonstrated in rigorous testing. Because the DURABIS coating technology rapidly discharges static electricity, the discs also resist the accumulation of dust.
