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.
Dubbed Blu-spec CD, the system uses a blue laser to write the audio data rather than a red laser. And... er... that"s it. The format delivers exactly the same recording capacity as a CD and uses the audio encoding mechanism enshrined in the CD bible, the so-called Red Book.
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.
