Neodymium magnets are the strongest in the world, that’s why they can be pricey. If you have an old hard drive (one you won’t ever need again), you can dismantle it to retrieve the neodymium magnets inside. Here I will give you a step-by-step guide for taking apart a computer hard drive.
Ordinarily, heat and electronics aren’t the best of companions; even less unsuited partners are heat and some magnetic materials! However, a new technology being developed by Seagate for the next generation of storage devices, known as ‘heat-assisted magnetic recording’ is breaking the convention. The technology is heralded as revolutionary and could significantly increase the amount of data that can be stored on a hard drive by increasing storage density.
