Sony Blu-spec CD Format Detailed, Hits Stores
CNETNate writes "More details about Sony's new Blu-spec CD format — standard CDs authored using Blu-ray's blue diode technology — are beginning to emerge, with commercial releases beginning to hit Amazon. Blu-spec CDs are compatible with existing CD players but have been mastered with higher levels of accuracy by using the same technology used to author Blu-ray discs, with the intention of eliminating reading errors that occur as a result of being authored with traditional red laser technology. Sony has also launched an official (Japanese) site for Blu-spec CDs."
If you RTFA, you'll notice the bottom half of it is titled:
Why this is all marketing nonsense
Funny how the summary left out that part.

Read the summary again. This isn't blu-ray, it's just using a blue laser to regular burn CDs instead of a red one.
It's solving a problem nobody has.
It's been a long time.
This isn't actually a new "physical media format". It's just a CD made with a blue laser instead of a red laser. They're still readable by any old CD player; the only difference is that they supposedly have a lower error rate.
My sig can beat up your sig.
Instead of that bullcr**, they could just stop reducing the dynamic range of our music and give us back the sound our CDs were supposed to produce...

CDs aren't created directly with lasers. The pit-land pattern is etched into a glass master, from which the stamps are produced which are used to press the polycarbonate discs that end up in our CD-players. The step which involves a laser is the activation of the photochemical surface of the glas master. Where the photochemical surface is washed away, the etching process creates the pits. I think it's a stretch to think that switching to a blue laser can provide a noticeable benefit in that process.
