A recently developed trick of light to bring microscopic images into sharper 3D focus, could be used to cram more data onto a blu-ray disc.
"An optical lens might appear to focus light to a fine point, but on the nanoscopic scale, the focal point is smeared out in the direction of light propagation – the beam's optical axis – to create a cigar-shaped cylinder. Improving that axial resolution is key to focusing clearly on nanoscopic layers within a sample under the microscope to pick out important detail. It could also allow lasers to focus more precisely within a Blu-ray disc, making it possible to squeeze more layers – and more data – onto each disc."

Hey :) Is it okay that I go sorta away from the subject? I am tryin to read the post on my brand new iPhone but it won't show properly (some of the boxes are pretty much gone), do you have any suggestions? Should I try and find an update for my system or something? Thanks in advance! Kanesha x :)
