A disk's surface is divided into concentric tracks (circles within circles), and the thinner the tracks, the more storage. The data bits are recorded as magnetic spots on the tracks in one orientation ...

Hot stuff Heat-assisted magnetic recording is set to boost the storage capacity of hard disks still further. (Courtesy: Seagate Technology) When it comes to storing data, you might think that magnetic ...

Three-dimensional magnetic vortices have recently been discovered. Vortex states are potential antennas for the ultrafast, wireless data transmission of tomorrow. hree-dimensional magnetic vortices ...

Quantum computers promise to tackle some of the most challenging problems facing humanity today. While much attention has been directed towards the computation of quantum information, the transduction ...

This release is available in German. Tiny magnets organize themselves in vortices in the researchers' mini disks. The individual magnets can twist either in a clockwise or a counterclockwise direction ...

The internal structure of a mechanical hard disk has a couple of components. It has a motor, a magnetic disk, a magnetic head arm, and a magnetic head. When the mechanical hard disk is working, the ...

In context: If there's one thing YouTube has shown, it's that almost anything can be built by yourself at home if you have the time, skill, and required parts. Take, for example, polymatt, who managed ...

Almost all computers today store their digital data as magnetic areas on a device called a hard disk, hard drive or fixed disk. Basically, all hard drives work the same way: Information is encoded and ...

(Nanowerk News) Three-dimensional magnetic vortices were discovered by scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Paul Scherrer Institute (PSI) ...
