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 ...

One of new bot’s features will be magnetic position encoders for the wheels. In the past, [Erich] has used the encoder disks that Pololu sells without issue. At 69¢ each, they don’t exactly ...

The computer's storage media prior to solid state drives (SSDs). Magnetic tape and disks were developed in the 1950s and commonly used together in companies for decades. Tape was the primary ...

Use less battery power - devices they are in stay charged for longer. Be more robust - a magnetic disk could be ruined by dropping it, because its moving parts may be damaged.

Researchers reveal a way to use antiferromagnets to create data-storage devices without moving parts. Scientists have ...

Magnetism itself may have given our solar system the architecture needed for habitability. A team at the University of Oxford ...

Black holes, often depicted as cosmic predators, have another fascinating role: they can launch some of the universe's most powerful explosions—gamma-ray bursts (GRBs). These bursts release more ...

It's a bit of a myth that black holes pull everything in. Much of the matter that finds itself falling towards the black hole is actually spat back out, thanks to powerful magnetic fields that are ...
