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
