et voila ce qu´on peux lire comme reponse dans le FAQS du site blu-ray.com
" 1.10 Will Blu-ray discs require a cartridge?
No, the development of new cost-effective hard-coating technologies has made the cartridge obsolete. Blu-ray will instead rely on hard-coating for protection, which when applied will make the discs even more resistant to scratches and fingerprints than todays DVDs, while still preserving the same look and feel. The adoption of hard-coating will also allow manufacturers to downsize players/drives and lower their overall media production costs"
voila, faut que j´en rajoute encore rhadamante
