TDK 50GB 2x BD-R Recordable Blu-ray Disc
Introducing TDK 50GB BD-R media, next-generation blue laser recordable discs offering massive storage capacity and blazingly fast transfer rates. From backing up large data directories to recording HD video, TDK Blu-ray Discs make it possible.

The high-sensitivity inorganic recording material utilized by TDK BD-R media is completely different than the recording materials used for CD or DVD. Composed of copper and silicon, TDK's exclusive CuSi recording material delivers remarkable, long-lasting performance. The recording material enables fast recording and playback speeds and also makes it possible to realize massive capacities through multi-layering.

DURABIS 2 protects the disc surface against scratches and resists smudges from fingerprints, providing error-free Blu-ray Disc performance. Hard coating technology pioneered by TDK is part of the Blu-ray specification, but only TDK has DURABIS 2, the most advanced hard coating formulation for Blu-ray Disc media.

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.
