WebFor hard drives, the magnetic alloys are typically CoPtCr (cobalt+platinum+chromium) with traces of boron or tantalum added at times to improve the stability of magnetic domains. On the right is a Transmission Electron Microscope (TEM) images of magnetic domains for hard drives from IBM research. The scale bar on the upper left is 10 nanometers ...
WebData is stored on a hard drive in binary code, using 1s and 0s. The information is spread out on the magnetic layer of the disk (s) and are read or written by the read heads that 'float' above the surface thanks to the layer of air produced by the ultra fast rotation of the disk. WebModern hard drive suffers from what's called superparamagnetism, which happens when magnetic grains on the disk are smaller than 10 nm in diameter. As a result, the hard drive …
