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.

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.
