The problem has been finding a suitable material. And now the Seagate-led team has, namely two FePt-C nanogranular films separated by a Ru-C spacer layer with a cubic crystal structure. Well, obviously!\u00a0<\/p>\n<p>Incidentally, if you happen to be a material science PhD, you can <a data-analytics-id=\"inline-link\" href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S1359645424002222?via%3Dihub\" target=\"_blank\" rel=\"noopener\">check out the full research paper here<\/a>. For everyone else, the Cliff Notes go something like this:<\/p>\n<p>By adjusting the laser power and magnetic fields during writing, the FePT layers can be addressed independently, thereby doubling capacity. If that wasn&apos;t impressive enough, the researchers reckon this approach can be applied to three-level recording and may even work at four levels.<\/p>\n<p>If so, you&apos;d be looking at a 10-platter hard drive with a rough capacity of about 240TB.
