Sony pitches blue-laser Compact Disc revival

Sony failed to tune the masses into its better-than-Compact-Disc format, Super Audio CD, so it's having another go, this time with technology derived from Blu-ray Disc.

The upshot: Blu-spec CDs can be played in old-style CD and DVD players, Sony Music Entertainment (SME), the giant's Japanese audio operation, said yesterday.
