- A 120mm-diameter HD DVD disc stores HD video and other data recorded onto it by a 405nm wavelength blue-violet laser.
- Made using a high-precision stamping instrument for narrower data track pitch and fine, sharp groove shape.
- High-precision disc molding and bonding technologies achieve stable mechanical and optical characteristics.
- Newly developed organic dye featuring a revolutionary recording mechanism matches the short wavelength laser.
- New HD-BCM (Bismuth Coupling Material) phase-change recording layer provides high S/N ratio and long archive life.
