Sony Unveils Blu-ray Laser Written Audio CDs

This is almost funny: it's digital people! That means in order to get better quality, you need larger data size (end of story!). As the cd format based on the wiki remains the same (hence same storage capacity) the only way to get better quality (ie. more data on the same media) is a stronger compression, but this would be unreadable with older players. Hence it's only an improved printing process that puts the same data onto the same old CD. I am sure my CD player will love me to death for having an easier time to read them, but that's the only upside other than media coverage.

@Lamboy - I understand the theory, which is that a CD with a more precisely aligned track is more likely to be read accurately, so the error rate should, in theory, be lower. However, a decent CD player reading a clean, unscratched CD which has been properly pressed using a standard mass production unit should read practically without any errors whatsoever, and I fail to see how that can be improved upon. Blu Spec discs will obviously still be prone to scratching, and the sampling rate and bit depth are necessarily no greater than for any other CDs (to maintain compatibility with existing players). I am happy to be proven wrong, but until someone demonstrates, repeatably, an ability to distinguish a Blu Spec disc from a "normal" CD produced from an identical source, using the same high-end hi-fi kit for each in a blind ABX test, I refuse to believe that Blu Spec will offer any benefit.

Ah audiophiles. They'll do anything to justify their outrageous outlay on components. Even NASA doesn't use technologies as expensive and wrapped up in marketing speak, and they are interested in measuring and controlling things FAR more subtle than audio.
As has been alluded in the posts, the master may be cut using a blue laser, but the mass production still uses stamping, which is where the majority of errors creep in and why all CD players have to have error correction on them. The same applies to DVD and Blu-Ray.
It won't make a blind bit of difference, yet we can expect to read reviews about how the discs bring a haunting new depth of realism to the Fast Food Rockers' Fast Food Song.
It's still 16 bit @ 44.1kHz. The human range is 20 bits (you absolutely cannot hear anything more than that) and anything more than 44.1kHz is a bit of a waste of time really (information theory will tell you that). I do agree that headphones and loudspeakers are worth a moderate amount of investment since they are the transducers that actually make a difference.
Still, if you've got the money to burn then good luck to you.

Presumably it only works if you also use directional cables...

(although if you install the cable the wrong way round it might play backwards)
