Sony has introduced a new Blue-spec CD standard. This basically seems to be a Blu-ray version of the good old music CD.
Although details about the new format, launched in Japan in November, are somewhat scant, we do know that users won't need a new player for Blu-spec CDs.
"The Blu-spec CD format boasts a new approach to the faithful reproduction of music by utilizing the leading-edge blue laser diode technologies optimized for the manufacturing of Blu-ray," according to CDJapan. The new discs' polycarbonate plastic, optimized for Blu-ray discs, is used "to ensure accurate reading of the data."
Sony doesn't claim that the Blu-spec CD sounds any better than a CD or how the new discs compare with Sony's previous and nearly dead super-CD format, Super Audio CD (SACD).
