Sony\'s new Blu-ray discs won\'t 
work with your old Blu-ray player
Hey, did you hear? Blu-ray is selling like gangbusters this year, already raking in over $330 million and accounting for 12.3% of sales revenue for packaged media, according to Blu-ray.com. You know a good way to kill said sales? Start a format war — with yourself!
Well, it's not a war yet, but it's going to be something that's hanging over Blu-ray owners' heads: Sony's new Blu-ray XL, or BDXL, doubles the capacity of its predecessor, but will not work with current Blu-ray players. BDXL boasts a capacity of up to 128GB (and 100GB on rewritable XL discs), thanks to the fact that it uses four readable layers per disc. Those added layers mean that current Blu-ray player lasers aren't powerful enough, however, and you'll need new hardware to read them all.
Before you throw your player out the window, take heart in the fact that consumers probably won't see these high-capacity discs for a while. Sony plans for them to be used in the professional sector where high volumes of data need to be pressed onto a single disc, such as in the medical-imaging or broadcast-media industries. That, and 3D movies should fit on current Blu-ray discs.
In the long run, it could mean interesting things for the world of Blu-ray, beyond just making consumers buy new players — not to mention making one of the best players on the market, the PlayStation 3, obsolete in this regard. The higher capacity of the BDXL format will allow for even higher-quality HD, multiple versions of a movie on the same disc, and even allow for simple improvements, such as putting more episodes of a TV show on a single disc, meaning you'll get more out of your Netflix rentals. It'll be interesting to see if the sheer volume of physical media manages to nudge out in front of streaming content once more, the latter of which is limited by bandwidth.
