TDK Blu-ray Discs are breakthrough recording technology from the only media company that's a founding member of the Blu-ray Disc Association. 25GB single-layer and 50GB dual-layer write-once and rewritable versions enable massive data backups and the highest resolution HD recording. TDK's exclusive DURABIS hard coating formulation protects the media surface against scratches and other contaminants that would destroy lesser discs, while the company's advanced spin coat manufacturing process and ultra-precise recording materials ensure pure recording perfection. TDK: We're making Blu-ray Discs a reality.

TDK is pleased to announce that its 25GB BD-R Blu-ray Disc media has received an International Consumer Electronics Show (CES) Innovations 2007 Design and Engineering Award from the Consumer Electronics Association (CEA). Sponsored by the CEA and endorsed by the Industrial Designers Society of America (IDSA), the Innovations Awards program is the industry’s most recognized, highlighting product advancements in technology, design and engineering.

Because Life Is High Definition
To help realize its massive storage capacities, the Blu-ray Disc utilizes a track pitch of just 0.32 microns. The track pitch is less than half that of a DVD and the diameter of the laser spot is approximately 80 percent smaller. The blue laser's short 405nm wavelength and the large 0.85 numerical aperture of the object lens further contribute to the Blu-ray Disc's high density storage capacities.
