New recording layer structure to achieve 100 year archival life

Newly developed layers which are extremely close-grained and hard to be affected by water and other material protect recording layers from both sides.

Double the durability of archival grade was verified by accelerated testing.

A newly developed, double-protective "Tough Coating" is used.

This double-protective coating consists of a highly rigid "hard coat" layer and a highly elastic "cover layer" to protect the disc from scratches, dust, stains, fingerprints, and pressure marks.
