Tiny Whiskers Make Huge Memory Storage - Charles Choi, Newsfactor
Imagine that normal magnetic sensors can read a signal that begins with a strength of 1 and swings between an "off" reading at 0.8 and "on" at 1.2. The new sensors can read a range that swings between minus 1000 and plus 1000. New, tiny magnetic sensors could help break a technical barrier to ushering in the next generation of computer disk storage capacity, researchers reported Friday. The sensors, filaments of nickel thinner than a wavelength of visible light, are capable of detecting extremely weak magnetic fields.
