1. Realize high-capacity optical disc in the digital age with features of 12cm in diameter and Max 50GB(dual layer) 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 Concept of Blu-ray Disc
