Due to Panasonic’s advanced phase change recording technology, the Archival Grade discs have an expected archival life of more than 50 years at a room temperature of 77°F and a relative humidity of 80%. The high durability of Panasonic Blu-ray Discs has been verified by TÜV Rheinland, the world- famous quality and safety certification institution. All archival discs will be inspected and certified to keep the professional quality, ensuring further enhanced durability.
All Archival discs adopt “Tough Coating”, a double protective layer with hard coat and cover layers for added durability and high elasticity. The new hard coat is designed with a harder material that is more resistant to scratches and fingerprints and offers superior repellency against water and oil. The elastic cover layer material protects against pressure marks. With this optimally balanced “Tough Coating,” the new discs offer greater reliability and easier handling under various conditions for professional use.
