POSSIBLU Making Blu-ray Discs a Reality PURE Recording Perfection 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 coating manufacturing process and ultra-precise recording materials ensure pure recording perfection. TDK: We’re making Blu-ray Discs a reality. TDK BLU-RAY DISCS TDK Blu-ray Discs deliver next-generation storage capacities in write-once and rewritable versions. 25GB

DURABIS hard coating for superior durability without a cartridge. 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 lens further contribute to the Blu-ray Disc’s high density storage capacities.

SPIN COATING PROCESS 1 TDK’s exclusive spin coating technology creates a cover layer with nano-precise smoothness, ensuring pure recording perfection. Only TDK utilizes this Liquid resin for the cover layer is dropped onto proprietary spin coating process. a rotating disc. PRODUCTION TECHNOLOGY FOR PRECISE PERFORMANCE A 0.1 millimeter thick cover layer comprises the Blu-ray Disc’s outermost layer, and the recording material resides beneath it. During recording, the laser passes through the cover layer in its path to the recording layer. Absolute uniformity in the thickness of the cover layer is critical to ensuring precise laser tracking, which is required for reliable performance.

TDK BLU-RAY DISC DISC WITH POOR COVER LAYER UNIFORMITY ROBUST DURABILITY Because the Blu-ray Disc employs high density recording, which requires maximum laser precision, the disc must be aggressively protected against scratches and other contaminants that could interfere with the laser, causing data errors. The solution is DURABIS, TDK’s exclusive hard coating technology.

SUPERIOR SCRATCH RESISTANCE DURABIS 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, the most advanced hard coating formulation for Blu-ray Disc media.

As shown, the fingerprint substance had far greater difficulty adhering to the disc with DURABIS, forming only minute particles that are too small to interfere with the laser. DURABIS 2 COATING WITHOUT HARD COATING REVOLUTIONARY RECORDING ELEMENTS TDK’s write-once and rewritable Blu-ray Discs feature exclusive recording materials optimized for each disc type. The high-sensitivity inorganic recording material utilized by TDK for the write-once type Blu-ray Disc 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.
