1. Realize high-capacity optical disc in the digital age with features

of 12cm in diameter and Max 50GB(dual layer)

- 4.5 hours recording of BS digital high-definition broadcasting

- adoption of 405nm-wavelength blue-violet laser, objective lens with 0.85 NA, and 0.1mm protection layer

2. Respond to digital broadcasting

- suitable format for digital broadcasting (MPEG-TS

recording)

- copyright protection system to prevent illegal copy

3. Broaden its world by creating format family

- expansion into a variety of media and application
