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 ...

Magnetic tape and disks were developed in the ... but they all gave way to USB storage (see USB drive). See optical disc. THIS DEFINITION IS FOR PERSONAL USE ONLY. All other reproduction requires ...

How it works Artist’s impression of how an ultrafast disruption of superconductivity in a YBCO thin film triggers an abrupt ...

Western Digital plans to launch a 40TB HDD in 2026 using HAMR technology, and is targeting even larger drives in the coming ...

Half a century later, magnetic tape remains surprisingly well-used in government. NASA uses it to back up vast amounts of ...

This has been the foundation for electronic applications of magnetic materials for the past 100 years, in the form of, for example, inductors, microwave isolators and magnetic disk drives.

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.

The pre-fab encoder disks don’t have individual magnets—they’re just a puck of magnetic slurry that gets its polarity on the assembly line. [Erich] reverse-engineered a disk and found the ...

When no magnetic field is applied, the disk accumulates a twist during self-assembling, which causes it to stop growing once it reaches a certain diameter. Applying a magnetic field to the viruses ...

Simulations of highly magnetized stars that explode and collapse into black holes show that they transfer their magnetic fields to the disk of swirling matter that forms around the new black hole.
