Will Blu-ray Discs require a
cartridge?
No, the development of new low cost
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 today's DVDs, while still preserving the same
look and feel. Blu-ray also adopts a new error correction system
which is more robust and efficient than the one used for DVDs.
