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 ...

The team has manipulated quantum bits, so-called qubits, by harnessing the magnetic field of magnons—wave-like excitations in ...

"But we knew this wasn't right because astronomical observations reveal that the disks are actually fluffy -- more like an angel (food) cake. Our simulation helped us understand that magnetic ...

Cosmic forensic experts are reconstructing the magnetic field around an infant star from the planet-forming disk of gas and dust around it. How do you dust a star for fingerprints? It's certainly ...

Makers of hard disk drives, under growing pressure from faster rivals, hope a breakthrough will keep it the dominant ...

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 ...

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.

However, previous studies, including those by Mitch Begelman, suggested that strong magnetic fields might stabilize these thin disks, but the details of their role in energy extraction and jet ...

Or maybe there’s a spot in the disk that is going bad, and the stronger magnetic field is required to reset the floppy’s field. Let us know your guess, or if you know the answer, fill us in!

ALMA observations of the protoplanetary disk around HD 142527. The white bars show the directions of the magnetic field revealed by the orientation of the dust grains. The strength of the magnetic ...

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 ...
