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 ...

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 ...

Black holes have been fascinating subjects of study, not just because they are cosmic vacuum cleaners, but also as engines of ...

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!

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.

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 ...

but so far it has not been possible to measure the magnetic fields in a protoplanetary disk. In this research, an international team of astronomers led by Satoshi Ohashi at the National ...
