                                  | Bigger hard drives mean cramming more bits 
                                    into smaller spaces. But the practice of simply 
                                    shrinking conventional bits is about to bump 
                                    up against the laws of physics. Storing information 
                                    using arrays of nanowires set on end, however, 
                                    could catapult disk drive capacities into 
                                    the stratosphere. All that stands in the way 
                                    is figuring out how to read and write to these 
                                    microscopic bits. Full
